Forms Recognizer action cannot be run with Optional features in the New Designer due to InvalidTemplate

[codyc1515]

Describe the Bug with repro steps

1. Create a Logic Apps "Form Recognizer" Connector with "Optional and Premium features" value of ["keyValuePairs"] - this is the only value I could find that work allow me to Save the Logic App .
2. When the Logic App runs, it fails with InvalidTemplate Unable to process template language expressions in action 'Analyze_PDF_using_AI_with_Invoice_model' inputs at line '0' and column '0': 'Error reading string. Unexpected token: StartArray. Path 'queries.features'.'.

This was working before in the Legacy Designer with the exact same values.

Standard (Portal)

This seems like a connector issue. The Schema we're given is expecting the parameter Optional and Premium features to be an array and thus our validation will prevent saving of this as so. I'm transferring this to backend and going to start an internal thread with the connector owner on their schema

Hi @codyc1515 while we work with the connector team on this, you add an expression token to skip the validation as so, which should allow it to save:
