I have a flow which intermittently fails. The failure occurs on the Compose step which converts data URI to binary. The data URI is passed from Powerapps after taking a picture using the Camera control.
I experienced this error twice since yesterday.
HI @Anonymous,
Could you please expand the "Compose" action within your flow?
Could you please show more details about the formula that you provided within the Inputs field of the "Compose" action?
I have made a test on my side, and don't have the issue that you mentioned. The screenshot as below:
Flow configuration:
Within the Inputs field of the "Compose" action, type the following formula:
dataUriToBinary(triggerBody()['Compose_Inputs'])
App configuration:
Set the OnSelect property of the Camera control to following formula:
ClearCollect(ImageCollection,Camera1.Photo)
Set the OnSelect property of the "Upload" button to following formula:
'20180914_case11'.Run(First(ImageCollection).Url)
Note: The '20180914_case11' represents the flow on my side.
Please check if you have passed proper value (Data url) from your app to the flow.
Please check and see if the following blog would help in your scenario:

In addition, if you want to upload pictures captured via the Camera control to Azure blob, you could also consider check the following blog:
