Hey there, emmaspivak.
Welcome to the Community space. I'm here to assist you with the error code you received in QuickBooks Online.
I need more information about the error code 150 you encountered in the system. Can you share with us the name of your bank? Are you receiving the code when clicking the Update option in Bank Feeds? Any additional information you could add would be a great help.
The Community team is on the lookout for your reply. I also encourage you to add some screenshot for our reference.
