Hi İzzettin,

Thanks for your interest. Complete log link is at below. It is happening when i try to deploy or update an environment.

I've encountered the error
AttributeError: 'method' object has no attribute '__yaql_function__'
in our environment recently. I believe it started after we upgraded to the Stein release.

I haven't tracked it down yet, but calls to the YAQL function:
std:Project.getEnvironmentOwner()
in a Murano app seem to generate it.

It's good to know that at least someone else has reproduced this.

cheers,
Andy
