After trying to manually run my flows, I sometimes get infinite loading on the “Execute Workflow” button, can’t stop it and if I refresh, all hell goes loose.
To get it running again, I’m cleaning manually the executions from my database running DELETE FROM execution_entity;, clear cache from browser (and initiate a new incognito session, because the old browser window is now doomed).
Sometimes I even need to recreate the docker container, as restarting does nothing.
What is the error message (if any)?

Access to n8n db is ok, host, user and password all functional.
Also, after this happens, If I refresh the page, I get a blank page and this in the console:
[Error] SyntaxError: No identifiers allowed directly after numeric literal
(anonymous function) (ParameterInputList-fe1383b3.js:53)
And in MariaDB logs I found a lot of these:
2023-03-05 18:26:21 160 [Warning] Aborted connection 160 to db: 'n8n' user: 'n8n' host: 'n8n-n8n-1.ee-global-backend-network' (Got an error reading communication packets)
Please share the workflow
It happens randomly on all flows.
Share the output returned by the last node
Flows don’t run anymore. Difficult to get it back running.

LE: In order to connect again to n8n web gui, I need to close the safari incognito and open a new one, as it seems the old session is broken for good
LE2: it’s even worse now. could not get back in no matter how many incognito’s I opened. Had to run again DELETE FROM execution_entity; in order to make access the web app again…
Hi @Cristi_Milea, I am very sorry to hear you’re having trouble. The error seems to be thrown by this file, with which I am unfortunately not familiar. Perhaps @netroy has an idea what might be causing these errors for you?
@Cristi_Milea This looks like there are some kind of connectivity issues between the n8n and mariadb.
That’s the reason behind the Got an error reading communication packets errors.
The The session "*" is not registered. errors are coming from the frontend disconnecting from the backend in the middle of a manual execution.
Can you please run a new docker-compose setup, and try to reproduce this issue there? That way we can (hopefully) isolate the issue, to be able to fix it.
