Hey everyone, after updating to the latest release i can’t start jobs via UI or SSH anymore. Any ideas? I power-cycled. The jobs are not even failing, they are not starting at all. Leo ---

Hi @LeoKleym, (Sorry I missed this post) Hm, so when you run `pio run stirring` on the command line, nothing happens? Can you tell me what ```auto which pio ``` returns? * * * Edit: also, how did you update? Via the release.zip or over the internet? ---

I’m having an issue with running jobs from the UI as well. Error code in pio logs is: ```auto 2025-07-24T12:24:22+0100 [pioreactorui-pioreactor01] ERROR Exception on /unit_api/jobs/run/job_name/dosing_automation [POST] Traceback (most recent call last): File "/usr/local/lib/python3.11/dist-packages/flask/app.py", line 1511, in wsgi_app response = self.full_dispatch_request() ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/local/lib/python3.11/dist-packages/flask/app.py", line 919, in full_dispatch_request rv = self.handle_user_exception(e) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/local/lib/python3.11/dist-packages/flask/app.py", line 917, in full_dispatch_request rv = self.dispatch_request() ^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/local/lib/python3.11/dist-packages/flask/app.py", line 902, in dispatch_request return self.ensure_sync(self.view_functions[rule.endpoint])(**view_args) # type: ignore[no-any-return] ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/var/www/pioreactorui/pioreactorui/unit_api.py", line 283, in run_job body = current_app.get_json(request.data, type=structs.ArgsOptionsEnvsConfigOverrides) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/var/www/pioreactorui/pioreactorui/ __init__.py", line 268, in loads return loads(obj, type=type) ^^^^^^^^^^^^^^^^^^^^^ msgspec.ValidationError: Expected `str`, got `null` - at `$.env[...]` 2025-07-24T12:24:22+0100 [huey.consumer] ERROR Could not post to pioreactor01's address='100.77.93.20'/endpoint='/unit_api/jobs/run/job_name/dosing_automation', sent json={'args': [], 'options': {'automation_name': 'chemostat', 'skip_first_run': 0, 'max_working_volume_ml': 10, 'initial_volume_ml': 10, 'duration': 20, 'exchange_volume_ml': 0.5}, 'config_overrides': [], 'env': {'EXPERIMENT': '2025-07-23Test', 'JOB_SOURCE': 'user', 'MODEL_NAME': None, 'MODEL_VERSION': None, 'ACTIVE': '1'}} and returned HTTP response returned error code 500.

Can you post the output of `pio version -v` on both the leader and the worker (pioreactor01)? ---

I think in your case, it’s the `'MODEL_NAME': None, 'MODEL_VERSION': None`. Can you try giving your Pioreactor some model on the Inventory page? ![Screenshot 2025-07-24 at 10.38.17 AM](https://forum.pioreactor.com/uploads/default/original/1X/ab3ea69d316bf867b2b2f9b6d11deaf4a4667fa6.png) I need to handle the edge case where you aren’t using a traditional Pioreactor model, like yourself. ---

Oh yes that fixed it thanks!
