Looking at the error yet knowing close to nothing about AYON my suspicion would be that the issue is still this:
STDOUT: !!! Please use ‘AYON_SERVER_URL’ to specify server address and ‘AYON_API_KEY’ to specify user’s token
I suspect that you deadline submission itself would have special environment variables submitted along that represent those values: AYON_SERVER_URL and AYON_API_KEY or that you need to specify these somewhere in the Ayon Deadline Plugin. I believe the latter is the default configuration workflow for AYON.
I suspect you need to go to Deadline:
- Tools > Enable Super User Mode
- Tools > Configure Plugins
- Find the (hopefully installed?) AYON plugin for Deadline.
- Configure the
AyonServerUrlandAyonApiKeyparameters
Which is basically Step 2 - Configure plugins from deadline menu Tools > Configure PLugins of the configuration described there where you can expand the Configure AYON plugin section. Which also explains the need for the Service User, generation of the API key, etc.
Admittedly, I missed that section at first too because it was collapsed and thus can be easy to overlook.
