Error: Unhandled error: SyntaxError: Unexpected token '{'

Hello!

I use this workflow element (To Reproduce section) to display the terraform plan, the variable ${{ steps.show-plan.outputs.stdout }} contains a string with special characters plus json elements.

How to avoid this issue? Probably I need to encode the string somehow ..

Tried including result-encoding: string but same result.
By the way, about a month ago this workflow worked fine.
