There have been multiple reports of class missions bugged and I've seen others report the same one for the Bounty Hunter before. I was not able to find any work around specifically for this. Some things you can try are the following:
1. make sure that treek or hk-51 is not the active companion. I know that using them sometimes causes class missions to glitch or no work. You would have to leave any instance your in, reset the mission and then use a bounty hunter companion.
2. Try running a repair:
Non-Streaming launcher - Log into the launcher but don't click Play. Check for small letters "ST" in the bottom left corner. If this is NOT present, With the new launcher after login , select the username pull down on the top right and select settings, then press repair.
Streaming launcher - If the letters "ST" is present, close the launcher, right mouse click on the game shortcut, select open file location and delete the BitRaider folder. Then start the launcher.
If that doesn't work the only option would be to submit an in-game ticket to see if they can fix the mission or advance it to the next part for you.
