Ok, then it seems like the Docusign standard connector requires the cryptic tab id.
The Power Automate step is called “Update envelope pre-fill tabs”, but it looks like you are not working with a pre-fill tab, but with a text field that is assigned to the first signer. This is then most likely the issue here. Try to remove the account name field, which is a recipient tab and add a pre-fill tab, which should then work.
Or you need to use a different action in Power Automate to update recipient tabs, not pre-fill tabs. if available in the standard connector.
