Error: Attribute redefined - The argument "tags" was already set

[cmrust]

I'm receiving the following error on module version 1.6.1:

Error: Attribute redefined

Each argument may be set only once.

It seems the tags attribute shouldn't be redeclared over and over here:

This seems to work fine for me with Terraform 0.11.11. What version of Terraform are you using?

[cmrust]

Hey @scholzj. Yep, looks like this error is specific to 0.12.0, which was just released. Rolled back to 0.11.14 and it's working fine again. To clarify above, this error was generated during a terraform init.

[scholzj]

Hmm, I will have a look if there is some workaround.

[scholzj]

FYI: I'm thinking about moving to Terraform 0.12.0 from Kubernetes 1.15. So that should be the timeframe I will look at this.

[scholzj]

@cmrust I finally found some time to upgrade to Kubernetes 1.15.x and Terraform 0.12.x. Please give try to the last release.
