Expired connection not reconnecting like it has for the previous 3 years on Microsoft Flow

Hi,

I got the dreaded flows failed due to ArcGIS connection breaking again.

I don't know if there is updated guidance on having this not happen. Breaks systems and ruins data.

But now, when I go to reconnect, it is saying that it can't. This has never happened before. @AkshayHarshe any thoughts?

Here is the error.

The request failed with client error: 'Input parameters are invalid. See details for more information. Details:errorCode: ParameterNotDefined. Message: Parameter 'token:clientSecret' is not allowed on the connection since it was not defined as a connection parameter when the API was registered.'. The correlation Id is 'e8bcc66a-d09b-4aa1-97e9-ce6115d2b9f0'.

Ok. Found the error on the new Microsoft Connections page. See attached if this happens to you. The Connections defaults to New Connections Experience page and gives an error when reconnecting. Have never had an issue before.

Switch the new experience off to get to the previous Connections Experience page. Hit reconnect. It asks to allow the connection to your ESRI account. All fixed.

@TimLohnes1 This looks fairly new, I do not see that toggle in my MS tenant and environment. Looks like new connection experience is on horizon. Thanks for this post, hope it will help others.
