[Geoserver-users] WFS Request Error - StringIndexOutOfBoundsException

Loigge_Bernd · December 2, 2019, 4:05pm

Hi,

We are facing an issue when making a wfs request without any filter for some polygon data. When requesting the same data using “application/json” or “GML2” as the outputFormat all data is provided. Also when requesting only the feature (using cql) at which the error is raised the valid feature is returned, so it doesn’t look like there is something wrong with the data.

At first we thought it could be because of the amount of requested data (around 30MB in GML2), but when requesting some other layer (which has far more data) we don’t get this error.

Result of the Request:

<gml:Polygon srsName=“urn:x-ogc:def:crs:EPSG:4326” srsDimension=“2”>

gml:exterior

gml:LinearRing

gml:posList

This looks like it will be a challenge to solve, the Encoder line 729 looks like this:

// here we check for instanceof EncoderDelegate
if (next instanceof EncoderDelegate) {
// do not add entry to the stack, just delegate to encode
try {
((EncoderDelegate) next).encode(handler);
} catch (Exception e) {
throw new RuntimeException(e);
}
}

···

Because the line number does not quite line up with any useful code need to ask you what version of geoserver you are running? Otherwise the stack trace does not help…
Still if failure is occurring here we may need to turn on very detailed logging (or use a debugger) to determine what is happening right when your error occurs.

Thank you for the quick response!

We are running version 2.16.0.

Using GEOSERVER_DEVELOPER_LOGGING returns the following log:
