Probably for the best. If you'd let him onboard it might have ended up like this story.

Obviously, I'm probably missing some context here, but reading the way you've described this, I don't think you were at fault here. If the GM's decision really was to fold that character into the group by just having them stroll up to a smuggler's ship like "Yo, I'm the jedi, let me in," that was an incredibly fucking stupid way to handle that character introduction.

If that happened in an actual Star Wars movie or TV show there would be a million youtube videos ripping on how stupid that scene was. Forget "Paranoid smuggler trying to evade the law", basically anyone working against the empire should have been suspicious as fuck there. That's not a jedi, that's an imperial spy, or worse, a sith lord.

Yes, players owe to each other to try to move the story forward in a collaborative way, but the GM also owes it to the players to never demand that their characters act like complete and total morons for the sake of the story. There should have been some kind of framework there for why this group of people would trust this random-ass dude wandering into the docking bay. A message sent ahead by their contact in the resistance saying "This guy is gonna help you out, you can trust him," something like that. Not just "Yo, I'm a party member, lemme in." Real life doesn't work like that, and when games try to work like that it just makes everything feel stupid and pointless, because it's so obvious that none of it is real or meaningful.
