Power Apps & Flow error

Today my application started to show the error: 


" ConfirmacaoFlow.Run com falha: Exception message: •Unknown error.' Exception call stack: Error at d (https://paplayercdn-int.azureedge,net/appresources/us5e9ftq29m9d/js/Core.js:1:15295) at f (https://paplayercdn-int.azureedge.neVappresources/us5e9ftq29m9d/js/Core.js:1:15371) at nO(https://paplayercdn-int.azureedge.neVappresources/us5e9ftq29m9d/js/Core.js:1:14697) at n.createFromArrayBuffer ([js/Core.js:1:74268) "


The error appears when I try to run the Microsof Flow called "ConfirmacaoFlow"


Can someone help me ? Tks!!

I am getting the exact same message on my apps as well.  The error only occurs when I load the app via webpage (not via mobile device app)


My 'FLOW' is simple which is to send an email out that contains some 'ask in powerapps' fields.

Our app started producing this error last friday when calling the flow throughout multiple screens in our app. The flow is a simple email flow, and we have change the connector from O365 to generic mail function during some troubleshooting and still receive the error. 


Anytime we call the flow now, the error attached blips briefly. The record is still written/modified and the flow still runs without errors but we receive a powerapps error. Any idea on what could be going on?




I am getting a similar error:

Comm.Run failed: Exception message: 'Unknown error.' Exception call stack: Error at d ( at f ( at Object.n [as checkNonEmpty] ( at Function.n.createFromArrayBuffer (…


And only in the Web Version of the App. 


The Flow is a Simple send email through O365 connection. The flow runs well, and the mail is sent, however we see this error
