Print labels "Request failed with status code 500" in 1.0.0 (stable)

[inscrut]

Hello everyone!

Label printing worked on version 0.18.0. After the update, label printing is completely broken; even the default labels don't work. The preview shows the error "Request failed with status code 500."

Unfortunately, that's all the server returns.

A huge question: until this is fixed, how can I roll back the update?

I'm using "Bare Metal" instead of Docker: https://docs.inventree.org/en/stable/start/installer/#file-locations

I couldn't find any documentation on how to upgrade to any other version. "inventree run invoke update" forces an update to 1.0.0 stable from an old commit.

Thanks!

Minimum information :(

Sorry, easy fix:

chown -R inventree:inventree /opt/inventree/

But... i hope this will be helpful for searching...

To avoid starting a new discussion, could you please tell me how to switch from the "stable 1.0.0" branch to the "master/latest" branch when installing "Bare Metal"?

I tried setting the "INVENTREE_TAG" tag, but inventree run invoke update doesn't update the version from 1.0.0 to 1.1.0 dev.

If you are running the bare metal install you need to pull down the latest branch in git
