[Geoserver-users] Error using function Interpolate in COLOR mode from SLD

GeoServer GeoServer User
1

Hi there,

I’ve updated one of our GeoServes from version 2.22.2 to latest stable 2.25.1. When requesting SLD-styled maps via WMS I’m getting this OWS exception:

Error rendering layer mga.bl: Trying to evaluate the function as Object but the method parameter is set as COLOR

I guess, it’s about the Interpolate function, which we use to vary line colors depending on wms_scale_denominator:

wms_scale_denominator 2132 #202020 17471320 #404040 color

There’s no longer any error after removing that function from SLDs.

The styles have not been changed. These used to work well with the 2.22.2 version.

I haven’t found any breaking changes in the documentation for filter function Interpolate. Actually, my SLD seems quite identical to what the documentation shows:

https://docs.geoserver.org/main/en/user/styling/sld/tipstricks/transformation-func.html#id2

Any help and ideas are very appreciated.

Cheers
Carsten

H there x 2,

That is quite a puzzle.

It may be a case of:

  1. Trying to reproduce the error with the standard data directory and making a bug report
  2. Trying the different version between 2.22.2 and 2.25.1 to see when it breaks (and then we could learn more)
    If doing this approach it is best to bisect debugging approach: take a version in the middle, and then you know to test higher or lower. Take in the middle of the new range etc…

Hi Jody,

why a puzzle? I’ve just checked this: The error is reproducible with the latest GeoServer main branch, by simply adding an Interpolate filter function in color mode to one of the standard SLD styles (e.g. simple_roads) in standard data directory.

Making CSSParameter stroke depend on wms_scale_denominator:

#AA3333 wms_scale_denominator 2132 #AA3333 17471320 #AA9999 color 2

leads to exception:

[…]

Seems like Class context does not implement Color It works fine if method is “numeric” (in contrast to “color”).

It is more that I am not aware of any change that could cause this regression.

Were you able to determine when the problem was introduced and report the issue to the issue tracker?

I am curious to what you will find. Determing which release the problem started in will help a great deal.

There isn’t enough of the stack trace provided but this commit is a possible source of the regression (GeoServer 2.23.3+): https://github.com/geotools/geotools/commit/d7991fdcd1630ea1c18b5dfad91d4e291b8bb95b

I had a look at this error and can confirm that it’s a legit error with the main branch. So an Issue in Jira would be welcomed.

Carsten provided two different sld. Here is the one I’ve been using:

wms_scale_denominator 2132 #AA3333 17471320 #AA9999 color 2

Subject: Re: [Geoserver-users] Error using function Interpolate in COLOR mode from SLD

This Message Is From an External Sender

Please use caution with links, attachments, and any requests for credentials.

It is more that I am not aware of any change that could cause this regression.

Were you able to determine when the problem was introduced and report the issue to the issue tracker?

I am curious to what you will find. Determing which release the problem started in will help a great deal.

Hi Jody,
why a puzzle? I’ve just checked this: The error is reproducible with the latest GeoServer main branch, by simply adding an Interpolate filter function in color mode to one of the standard SLD styles (e.g. simple_roads) in standard data directory.
Making CSSParameter stroke depend on wms_scale_denominator:

#AA3333 wms_scale_denominator 2132 #AA3333 17471320 #AA9999 color 2 leads to exception: [...] Caused by: java.lang.IllegalArgumentException: Trying to evaluate the function as Object but the method parameter is set as COLOR at org.geotools.filter.function.InterpolateFunction.evaluate(InterpolateFunction.java:323) at org.geotools.filter.function.InterpolateFunction.evaluate(InterpolateFunction.java:301) at org.geotools.filter.visitor.SimplifyingFilterVisitor.visit(SimplifyingFilterVisitor.java:484) at org.geotools.filter.function.InterpolateFunction.accept(InterpolateFunction.java:296) at org.geotools.styling.visitor.DuplicatingStyleVisitor.copy(DuplicatingStyleVisitor.java:379) at org.geotools.styling.visitor.DuplicatingStyleVisitor.visit(DuplicatingStyleVisitor.java:655) at org.geotools.styling.StrokeImpl.accept(StrokeImpl.java:420) [....] thrown here: [https://github.com/geotools/geotools/blob/f0c9961dc4d40c5acfce2169fab92805738de5ea/modules/library/main/src/main/java/org/geotools/filter/function/InterpolateFunction.java#L320](https://urldefense.us/v3/__https://github.com/geotools/geotools/blob/f0c9961dc4d40c5acfce2169fab92805738de5ea/modules/library/main/src/main/java/org/geotools/filter/function/InterpolateFunction.java*L320__;Iw!!JRQnnSFuzw7wjAKq6ti6!xut7MRht1ecLGteZ1aKGg5roShoUSjG5tqvW0u3NMBIcQXEZEhSwHmbskJ-MFnqjKx-G314NqB5naHhV1L1EZOg$) Seems like *Class context* does not implement *Color* It works fine if method is "numeric" (in contrast to "color").

H there x 2,

That is quite a puzzle.

It may be a case of:

  1. Trying to reproduce the error with the standard data directory and making a bug report
  2. Trying the different version between 2.22.2 and 2.25.1 to see when it breaks (and then we could learn more)
    If doing this approach it is best to bisect debugging approach: take a version in the middle, and then you know to test higher or lower. Take in the middle of the new range etc…

Hi there,
I’ve updated one of our GeoServes from version 2.22.2 to latest stable 2.25.1. When requesting SLD-styled maps via WMS I’m getting this OWS exception:
Error rendering layer mga.bl: Trying to evaluate the function as Object but the method parameter is set as COLOR
I guess, it’s about the Interpolate function, which we use to vary line colors depending on wms_scale_denominator:

wms_scale_denominator 2132 #202020 17471320 #404040 color

There’s no longer any error after removing that function from SLDs.
The styles have not been changed. These used to work well with the 2.22.2 version.
I haven’t found any breaking changes in the documentation for filter function Interpolate. Actually, my SLD seems quite identical to what the documentation shows:
https://docs.geoserver.org/main/en/user/styling/sld/tipstricks/transformation-func.html#id2
Any help and ideas are very appreciated.

Cheers
Carsten

Hello there,

I exactly have the same issue: has someone already created a JIRA ticket? I haven’t found one so I would like to confirm the fact before creating one.

Hello Alexandre,

I haven’t yet created a JIRA ticket as I’m quite busy at the moment. Also, due to lack of time, I wasn’t able to track down the exact version which first introduced this issue.

Hi Steve,
yes, that commit is involved, as it triggers a bug in the function implementation.
A function must not rely on the context object being set, the context is provided only so that the function can try to covert

its result towards it. Passing in “null” or “object” means “do what you want, we’re not asking for a particular type of output”,
but the current implementation throws an exception instead. Looks like the error predates the git history (14+ years)
In any case, that needs to be fixed.
