AuthType=ClientSecret without secret attempts interactive authentication (Connection String)

[fowl2]

I forgot the secret in my `AuthType=ClientSecret;ClientId=aaaaaa-bbbb-cccc-ddddd" connection string, and was confused by an error refering to interactive authentication:

Unable to connect to Dataverse: Showing a modal dialog box or form when the application is not running in UserInteractive mode is not a valid operation. Specify the ServiceNotification or DefaultDesktopOnly style to display a notification from a service application.

If interactive authentication were possible I imagine I'd be even more confused by my code running as an unexpected principal

It'd be great if there was a specific error message for a missing secret.

Interesting, that error is coming from MSAL itself, the verbose error should have included the MSAL Error code.
did it? ( it would be in the error dump )

Doesn't appear so?

Here's the full (slightly redacted) logs I've got:
