Calling Actions from Copilot Studio

Yes/No input parameter is not available in dynamic content

Posted on by 17

As the title states:


I have a Yes/No input parameter inside my flow that I am calling from PVA, however the variable for this parameter does not appear in the list of dynamic content for the subsequent steps.


I see this thread suggests clicking on "more", but I do not have this option.




I have also tried using the variables function variables('InternalRequestBool') to no avail as this is meant for interacting with actual variables, not input/output parameters as explained by the error message I encountered when trying to save the flow with this code:


Request to XRM API failed with error: 'Message: Flow client error returned with status code "BadRequest" and details "{"error":{"code":"InvalidOpenApiFlow","message":"Flow save failed with code 'InvalidVariableOperation' and message 'The inputs of workflow run action 'Send_an_email_notification_(V3)' of type 'OpenApiConnection' are not valid. The variable 'InternalRequestBool' must be initialized before it can be used inside action 'Send_an_email_notification_(V3)'.'."}}"


Is this a known issue/limitation? I cannot see anything about it in the documentation.


Yes I could use a text field with a dropdown set of options but the boolean type seems made for this kind of thing.


Any advice would be appreciated.

    Thank you for this solution @renatoromao. Is there some documentation that you can link to that explains why this is required for the Yes/No input parameter type and not the Text or Number types?


    Below is a screenshot of how I configured everything in case someone else comes across this in the future.

    Hi @MattStannett ,


    Create an action after the trigger card (PVA) in the Power Automate called Compose.

    Rename this action to your variable name, just to best practice. And inside the action, select the yes/no field using the dynamic content.


    If you like this reply, please give kudos. And if this solves your problem, please accept this reply as the solution.
