ArtifactStore: Error while Uploading Custom Artifacts via GRR UI

See original GitHub issue
Hi,
so we had some custom artifacts in our artifacst store of GRR Version 3.2.3.2.
After deleting the artifacts via GRR-UI we wanted to upload a newer version to the GRR-Server using the ui.
Unfortunately this is not possible because we get the following error as soon as we open the Artifact Store in the Web UI:
Traceback (most recent call last):

We also tried to delete the Artifacts using the grr_console. But this seems not to help. Also when we use the grr_config_updater tool it won’t work.
Do you have any clue what the problem is, because we use another server with the exact same version of grr and the same artifacts but no error occurs.
Thanks for your help, Sven

Hi Misha,

Sorry it was a typo because of my mobile phone. The Execution of In [1]: aff4.FACTORY.Delete(“aff4:/artifact_store”) did not delete the artifact_store in the sqlite database.
The error happened again. And also In [1]: aff4.FACTORY.Delete("aff4:/artifact_store") did not work. I had to delete the sqlite database from the system. Could you please check why the deletion in grr_console does not work?

This should be fixed now, also the issue references the deprecated aff4 data store so this is obsolete anyways.
