Hi, I have created a simple flow for OCR image to text analysis (Thanks to this video from Paul - https://www.youtube.com/watch?v=qXSRKfYqYMM). My flow image is attached. My flow is to be triggered by PowerApps and has 1 "Ask in PowerApps". When I run the flow from PowerApps, I see an error of invalid arguments, which says, expected 0, received 1. I tried creating a new flow, closing app, flow tabs but it remains the same. How can this error be resolved.

Hi @Anonymous,

It seems that we are not able to upload image when using Chrome, please try with IE which is working fine.

According to your description, I have established a flow which is triggered by a PowerApps button. Following by the action Send an email. I select dynamic content “Ask in PowerApps” from the trigger for the To field.

Screenshot for your reference:

Then add the flow on a button on PowerApps, set OnSelect property of the button with the following code:

'PowerApp->Sendanemail'.Run(TextInput1.Text)

When I click the button to trigger the flow, it runs successfully and email could be sent to the user I specified in the box.

Please take it for a reference and try it on your side.

Best regards,

Mabel

@v-yamao-msft, Thanks for your response ! Your example works perfectly and I have done this many a times in my PowerApps jouney. What I observed is that flows which are dealing with Azure blob, OCR connections are the one where this issue is faced. Such flows are expecting arguments (I even tried 2 arguments in flow to be passed from PowerApps) but powerapps is failing to recognize it. Check my another post - https://powerusers.microsoft.com/t5/Creating-Apps/Powerapps-flow-run-shows-no-parameter-expected/m-p/201220

Hi @Anonymous,

When adding the flow to a button on PowerApps, does it ask you to specify a parameter for the flow?

Could you share a screenshot on PowerApps?

Best regards,

Mabel
