Hi @karl_oliverio ,
Could you please share a screenshot about your flow's configuration?
Do you have passed proper value (e.g. 'a,b,c,d, ...') from your app to your flow?
Further, do you set the Type field to Array within the "Initialize variable" action in your flow?
I have made a test on my side, and don't have the issue that you mentioned. Please take a try with the following workaround:
App's configuration as below:
Flow''s configuration as below:
The flow executes successfully as below:
Please consider re-create a flow based on above solution I provided, then check if the issue is solved.
Note: Please add a "Compose" action within your flow to retrieve the passed string value from your app, then within your flow, split the string value into an array based on the output of the "Compose" action.
I also made a test based on your flow's configuration, but if I specify the parameter within the "Initialize variable" action directly, I could not create a connection to the flow from my app, it would show "Register error".
Best regards,
