base64tobinary

Re: Initiated Power App to Power Automate (Flow) within Power Apps, Solutions component. 

This really should be relatively easy to solve yet it's proving impossible.

File Name - triggerBody()['Createfile_FileName'].jpg

File Content - base64ToBinary(triggerBody()['Createfile_FileContent'])

Returns the following: 

InvalidTemplate. Unable to process template language expressions in action 'Create_file' inputs at line '0' and column '0': 'The template language function 'base64ToBinary' was invoked with a parameter that is not valid. The value cannot be decoded from base64 representation.'.

Why is this not working?

Please if possible provide elementary step-by-step solution instructions as to why this isn't functioning. ie. unambiguous how to fix instructions.   

I would add building Flow within Power Automate and then test it works yet I cannot add the flow to Power Automate.

Thank you.

Hi @CABIRD 

Please try dataUriToBinary to replace base64ToBinary.

I think this link will help you:

power automate - Sending Images from PowerApps to Microsoft Flow - Stack Overflow

Thank you.

I really appreciate you taking the time to reply.

In a previous app, this method worked.

So the question is why not now? 

The new app has been created in Power Apps>Solutions. 

I think there must be an error in the Power Apps connection to Power Automate. 

Create Power Automate flow in flow. Return to Power Automate to add the flow and the flows in Power Automate are not displayed to select see below.

Open another Power App (not from Solutions) and it is possible to add any Flow from Power Automate. 

Return to Power Apps (app in solutions). Click the create a flow button and rebuild the flow. The flow is displayed in Power Apps and connected. However, the connected flow fails.

Open Power Automate to view the flow history.  Edit the flow in Power Automate or in Power Apps and test. Cannot get the flow to function.

Delete and create again and it fails. Yet it is an exact copy (expect flow name) of a functioning and working flow created in Power Automate. 

Try to search for flow

Could not find flow '03dbdc92-c615-5752-0678-86219a2de1d1'.
code: FlowNotFound

How can this be fixed?

@v-liwei-msft I received an email requesting information as to whether the issue has been resolved. Sadly no. 

I updated the question the day I received a possible answer with additional information and await a reply (see below).

I look forward to learning how this issue can be resolved.
