To Reproduce

Use our code and do a terraform plan against a valid commercetools project. Please see if you can spot the problem already with the help of the output in previous section. We want to hand out as less code as possible. If really required i can try to provide the responsible snippets

Expected behavior

A terraform plan run without errors

Screenshots

n/a, see log output on previous answers

Addition: While we experience this bug in one commercetools project, we have two other ones, which work fine with the identical terraform code. This is really strange.

[demeyerthom]

Hi @timdeluxe it looks like the project settings for the failing projects are somehow out of sync with terraform, and that the provider for whatever reason cannot read or update them. I know that the project settings resource causes issues occasionally because it returns default values for fields even if not set in terraform, which trips up the provider.

Is the failing project an older one? And what happens if you set that project's settings additional fields with the general defaults?

[timdeluxe]

@demeyerthom One developer found a setting in the commercetool project, which we did not manage via terraform. Cleaning up that setting solved the issue with the provider. So basically we solved it by ourselves, sorry for not updating this issue yet. Therefore i am closing this issue.

If you are interested i can ask the developer, what exactly he had cleaned up. Please update here, if you are interested in that.
