[ZOO-Discuss] Error when running GRASS processes

[Gérald Fenoy]

Hi Pierre,
Nice to hear from you.

First of all, some times ago we've tested the GRASS Services you are trying to use on your computer so I can confirm your tests should succeed.

As the message coming back from the ZOO-Kernel in this case is not verbose enough, I suggest to try the same request you're using from the command line to see more details displayed. Another way to get more information about the reason why the ZOO-Kernel can't load the GRASS Service would be to take a look at the Apache error log and check if there is more details here. Using tail -f apache_error.log should be goos as you can see only informations relative to your current Service.

I'm pretty sure this will give you enough informations about the issue whicj happened. Please, give us this detailled informations and I'm surewe can help.

Waiting for your answer,
Best regards,
