Unable to select reconstruction and auxiliary lanes

Hello. We are unable to select a reconstruction or auxiliary lane. We can open the dropdown and pick one of our two lanes, but when we navigate to another window/menu and come back the dropdown is empty again. Preprocessing is working fine with both lanes. Non-live jobs are also able to run on both lanes.

global config variables:
export CRYOSPARC_LICENSE_ID="{redacted}"
export CRYOSPARC_DB_PATH="/troll/scratch/cryosparc/cryosparc_database"

and here are our lanes:

cryosparc@troll:/troll/scratch/cryosparc/cryosparc_worker$ cryosparcm cli "get_scheduler_lanes()"

  {'desc': '', 'name': 'askeladden', 'title': 'askeladden', 'type': 'node'}, 
  {'desc': '', 'name': 'troll', 'title': 'troll', 'type': 'node'}

I was just able to launch the streaming 2D job from within “normal” cryoSPARC. Still not sure why we weren’t able to select the lane in the config menu.

Please can you email us a compressed copy of

Hi @posertinlab, which Project and Session is this issue happening in? Do you have this issue in all sessions, or just this one?

Other sessions we’ve started since this issue have not had the problem. It was in P39 S3.

Hey @posertinlab, this is definitely weird, and unfortunately I haven’t been able to figure this one out- please let me know if it happens again.
