Need help with Xibo canva

Hello, I’m running xibo on AWS aws ubuntu, the installion is a non-docker.
Everything is working fine, except when I tried to connect Canva, I got the following:
{“error”:0,“message”:“API configuration problem, consult your administrator”}

Under advanced > log
I do not see anything.

Not sure where Xibo store the logs for non-docker installation.

Also, not sure why this error keeps showing. any idea?
