OpenApiConnection Error: inputs.parameters Invalid

I encountered a Power Automate error due to a name parameter exceeding the field length. Resolved it by updating the column size, reloading parameters, and saving the flow. A potential bug; the workaround worked seamlessly after adjustments.

I got the below error message while testing a scenario in Power Automate.

The ‘inputs.parameters’ of workflow operation ‘Create_Credit_Memo’ of type ‘OpenApiConnection’ is not valid. Error details: The API operation ‘CreateRecord’ requires the property ‘item/arun_name’ to be a string of maximum length ‘100’ but is of length ‘104’.

By looking at the error, we can easily understand that the supplied Name parameter is exceeding the Dataverse field maximum length.

Immediately, I opened the required solution. Clicked on the required column in the Table and updated the field length from 100 to 200.

Saved the column and published the Table.

I thought the issue was resolved and Tested the scenario again, but still the Power Automate was showing the same issue again.

I did not understand the issue now, even though the size of the Name column is less than 200, still showing this issue, after the Publish All Customizations as well.

I gave a try and changed the Table name from Credit Memo to Contact.

The table name is changed to Contacts.

Without Save, I changed it back to Credit Memos (required table) and all the parameters were reloaded.

After that, I saved the Flow, and then the flow started working as expected without any error.

Seems like this is some kind of a bug in Power Automate and hope it will be resolved in future releases.

I hope you have followed this trick and resolved this issue.
