Error - Maximum call stack size exceeded

[baenio]

Description and expected behavior After trying to upgrade ZenStack to v2, I discovered a bug when trying to call /api/model/membership/findMany (see error message). Every other table was working fine, expect Membership.

After some digging I found out, that it was a field level access policy causing the issue: @deny("read, update", space.memberships?[auth() == user && !(role in [owner, admin, roleManager])]) After removing the read part, it was working just fine.

This policy was working just fine in v1 of ZenStack, but I tried every v2 release and in every version the error occured.

Error

Hi @iamfj @baenie , could you try if the new 2.1.1 release fixed the issue?
