Scan Barcode

[SchrodingersGat]

Discussed in https://github.com/inventree/InvenTree/discussions/3126

^{Originally posted by **lookme2** June 3, 2022} I'm not sure this is a bug or not. So I thought I would start here. After updating to 7.0 and trying to scan a barcode I get "Server error" The question is do I have something setup wrong? I seem to remember something about this moving to a plug in but cant seem to find that in the docs Frankie

@lookme2 you should be able to view the error message in the admin view: https://inventree.readthedocs.io/en/latest/settings/logs/

Can you please post the error message here?

yes I have updated to 0.7.0 and when I scan via the web page I get "Server error" back. The scan does not work.

Are you using the main barcode scanning view from the navbar? And using the USB scanner functionality, or the "scan via webcam" feature?

@SchrodingersGat I am away from the server until Friday. I will post the log file then.

@SchrodingersGat here is what I see as the error from the admin page.

Are you running in docker, or a "bare metal" install?

[matmair]

@lookme2 git is missing on the system - curious that this point is reached. Could you: A) install git B) post the Version Information?

[lookme2]

Version Information:

InvenTree-Version: 0.7.0 Django Version: 3.2.13

Database: sqlite3 Debug-Mode: True Deployed using Docker: False

@matmair this was working fine until I updated to 0.7.0. I will install git.

[matmair]

@lookme2 is it working now?

[SchrodingersGat]

@lookme2 I think this should be sorted now, please let us know if installing git did not fix the issue.
