Create a new App Password
Create a new starter pack from the Profile tab of your account. Add seven random accounts so it can save. Perform the import. Remove the original seven random accounts.
*Note: A Starter Pack tops out at 150 members, so only 142 will be imported (150 minus you minus the 7 randoms)
Link to source code. I'm not logging anything on this server, at least not on purpose, but you should still probably use an App Password then delete it when you're done.
Also, feel free to follow me or reach out if anything seems amiss.
Also, also, the National Weather Service BSky bots that started this whole thing for me.
