Hi @Anonymous,
How many parameter values do you want to pass from your app to your flow?
Based on the error message that you provided, it seems to tell that you specified two parameters (that you want to pass from your app) within your flow, but you provided only one value within the ClearSSMField.Run() function.
Please check if you have specified two parameters (that you want to pass from your app) within your flow.
In addition, please also check if you have provided proper parameter values for the arguments of your ClearSSMField.Run() function.
If the issue still exists, please consider take a try to re-create your app, then add the new flow connection within your app, try it again, check if the issue is solved.
More details about passing parameter values from an app to a flow, please check the following article:
