[Zoo-discuss] Using gdal_warp service fails sometimes

[Fenoy Gerald]

Hi Thomas,
sorry for late reply.

Thanks a lot for you report. May I ask you to send the request you have used to face the issue ?

You are right mentioning that the issue seems to come from the ZOO-Kernel when it output the XML result.

I would like to know if the issue only occurs by changing the input data or depend on the output format specified ?

I hope to hear back from you for being able to solve the issue.

Best regards,
