Error using Form in Web Block

Error using Form in Web Block

  
Hi everybody,
When we try to import a Web Block with a form the platform show us an error, then all imports we try after that give us the same error. A workaround is using Edit Record instead Forms.

Platform Version: 9.0.0.11
Development Version: 9.0.0.7
Hello Marcel
