The flows I have worked well until they stopped working end of January. My Docker container gets updated automatically, so maybe there was a regression?

[caco3]

To reproduce it:

1. Grab the latest docker container from https://registry.hub.docker.com/_/nextcloud/ and set it up
2. Install the Workflow external scripts. I had it in version 1.3.1
3. Try to create a flow with it.

I tried several commands, but they all end up with The configuration is invalid:

• true
• echo %i
• ls
• /bin/true

@blizzz @juliushaertl Please give some advice

[caco3]

So after deeply digging into the code, namely Rule.vue, I found out that the text No events are chosen under the error message actually are part of the error message...

Now, since the rules worked before, I didn't expect that they suddenly miss data and stop working without any notification! It would be much easier for users, if the problematic field somehow would get highlighted!

My next step normally would be to create a follow-up feature request. How ever since on nextcloud the devs don't care for them, I think it would be a waste of time :(

@caco3 That would still be appreciated. Please don't make assumptions like that just based on a delayed reply. My github notification backlog is quite big, so please understand that it sometimes just takes a while until we get to see that message and reply to it.

[juliushaertl]

Regarding the actual issue, it is true that we generally don't allow flow rules without an event unless they have their own event handling implemented like files_accesscontrol. But we should look into that at the server repo.

[caco3]

That would still be appreciated. Please don't make assumptions like that just based on a delayed reply.

nextcloud/updater#158 (comment) sadly proves different :(

The issue still exists and no dev was willing to support tracing the issue further down.

Has this bug been fixed at any point? Because I just try to set up a workflow and get the error "The configuration is invalid" - I use version 26.0.2.
