External DB collection fails provision request

I try external collection.
I have launched your service on Google Cloud
github. com/wix/corvid-external-db-mysql-adapter
And when I try to add according to this instruction:
support.wix .com/en/article/corvid-working-with-external-database-collections

I see this error.

How to fix it?

The request is visible on the service and no errors occur.

Same problem here?

I think no

Does this help?
