power automate connector 'create flow' failure: 'OpenApiConnection' should not have the property 'authentication'

I have build a flow that could create a new flow using the 'Create flow' connector.
It uses the flow definition and connection reference, I obtain from a 'Get flow' connector.


I used an excellent tutorial from @JohnLiu  to do this.

At the moment when I build the flow, the connector was represented using this icon.


Last week I changed the 'power automate' connection to our service account and then the icon of the connector changed to this:



Now with the very same flow where I get my definition from a 'Get flow', the creation fails. 



Flow save failed with code 'WorkflowRunActionInputsInvalidProperty' and message 'The 'inputs' of workflow run action 'Create_Flow' of type 'OpenApiConnection' should not have the property 'authentication'.'.



I believe the previous version of the connector was: 


The new version is: 
Does anyone have an idea where I can find, what is changed and updated in this version of the connector?

This breaks on several fronts - Get File Properties, Approvals. It renders the update flow and create flow power automate management actions unusable.


Would it be possible to get an update on this?

I am facing similar issue with Window Mail Notification action. I have tried creating a new connection, deleted and recreated the connection but to no avail. One thing that I have noticed though is that the "Create Flow" actions works for simple Flow Definitions which does not have branches and multiple if-else or switch-case conditions. Not sure if there is any limitation or bug with the Create Flow action on using complex Flow Definitions. Any help in this regard will be greatly appreaciated.

I ran into the same error, and after quite a lot of trial-and-error, I managed to find a solution that worked for me.

What I did, is that I took the connection references of the retrieved flow, and copied them to the new flow.


The retrieved flow:

Connection References of the retrieved flowConnection References of the retrieved flow

And inserted into the new flow:

The settings of the new flowThe settings of the new flow

And this worked! You could make these dynamic, but I know that the connections are not going to change in my case. And be sure to use the same account for the connections in both flows. I don't know for certain, but that could also cause some issues.


I hope this will work for you!

Came across the same issue with "HTML to Text conversion" and "Notification to mobile phone" but the workaround from @KRademacher doesn't work for me. Any other ideas how to solve this?
