[gdal-dev] OGR2OGR WFS HTTP 504 but no ERRORLEVEL

[Langford, Robert]

Hi there,

Currently we have a process that loads data from an external WFS into Postgres from a nightly scheduled batch file on a Windows box.  Usually works fine and it reports on any errors that it encounters.  But recently we've been getting an HTTP 504 error and no features are written but the resultant ERRORLEVEL is still 0.

We've contacted the provider to hopefully resolve the error, but we were wondering why ogr2ogr isn't raising the ERRORLEVEL?

Currently using: GDAL 2.2.2

The WFS URL is:
"WFS:http://environment.data.gov.uk/ds/wfs?SERVICE=WFS&INTERFACE=ENVIRONMENTWFS--0896250c-3aaa-43e2-b783-a133522cb5e3&VERSION=1.0.0"

The layer name is:
ne_wfs_crow_act_2000_access_layer_england

Here's the metadata<http://environment.data.gov.uk/ds/catalogue/#/0896250c-3aaa-43e2-b783-a133522cb5e3>

A layer that works from the same service as an example is below:
"WFS:http://environment.data.gov.uk/ds/wfs?SERVICE=WFS&INTERFACE=ENVIRONMENTWFS--e819098e-e248-4a8f-b684-5a21ca521b9b&VERSION=1.0.0"
ne_wfs_national_parks_england

Command we're running is like:
ogr2ogr -append -f PostgreSQL %POSTGRES_CONNECTION% "WFS:http://environment.data.gov.uk/ds/wfs?SERVICE=WFS&INTERFACE=ENVIRONMENTWFS--0896250c-3aaa-43e2-b783-a133522cb5e3&VERSION=1.0.0" ne_wfs_crow_act_2000_access_layer_england -nln %POSTGRES_DESTINATION_TABLE% -preserve_fid --config OGR_TRUNCATE YES

Running the command manually gives the below error messages:
ERROR 1: HTTP error code : 504
ERROR 1: Error returned by server : HTTP error code : 504 (0)

(And with --debug ON you can find out "GDALVectorTranslate: 0 features written in layer"

But the %ERRORLEVEL% = 0

Could anyone advise if this a bug, or if not how we can detect such errors?

Many thanks,

Rob
