Forest "Request Entity Too Large" error when updating .forestadmin-schema.json

Help me!

Feature(s) impacted

Update of models schema on Forest

Observed behavior

When deploying a new version of our Forest agent, synchronization of .forestadmin-schema.json file fails with Forest servers with error “413 Request Entity Too Large”. Error started to ocurre less than a week ago, and sometimes after a few retries it ends up working, but not always.
File is about 1.6Mo.
Seems like a Forest server file upload limit or something..

Expected behavior

When the .forestadmin-schema.json is regerated or when the Forest agent starts, it should send it to Forest server for sync, and it should succeed

Hello @Matthieu_Delanoe and @Nicolas_Moreau,

Sorry for the late reply, we’ve been working on this nonetheless.
This issue as reported is linked to a limitation on payload size to request forwarded to our server.

We were able to rollback to the previous infra, we are already seeing some users successfully posting their schema.

Please try again, if you’re still experiencing the issue maybe clearing the DNS resolution cache might help.

Keep us updated if you’re still stuck,

Sorry for the inconvenience,

Best regards,
