Argument #1 ($projectId) must be of type string

[brot]

Since the update to 4.1.2 cospend is broken for me, because it's not able to load the projects

"Exception": "TypeError",
"Message": "OCA\\Cospend\\Service\\LocalProjectService::getProjectInfo(): Argument #1 ($projectId) must be of type string, int given, called in /var/www/html/custom_apps/cospend/lib/Service/LocalProjectService.php on line 1808",

Do you by any chance have project IDs that are numbers? You can check that in the database with:
SELECT id FROM oc_cospend_projects;

Can you try adding
$projectId = (string)$projectId;
between line 1807 and 1808 of lib/Service/LocalProjectService.php?
It would look like:

foreach ($projectIds as $projectId) {
	$projectId = (string)$projectId;
	$project = $this->getProjectInfo($projectId);
	$project['myaccesslevel'] = $this->getUserMaxAccessLevel($userId, $projectId);
	$projects[] = $project;
}

That is most likely the right fix for your issue. I could reproduce by creating a project with a numerical name so the ID ends up being a numerical string as well. There's a strange side effect of Php's array_keys function that casts numerical string keys to int. I'll check if this can happen in some other places.

Adding $projectId = (string)$projectId; worked.

And running the query SELECT id FROM oc_cospend_projects; returns two IDs: 1 and 2.
What should a non numeric id look like? The ID was not chosen by me, right?

What I forgot to say in my first comment is that I'm using Postgres 18.6.1 as my database. Maybe the database makes a difference?!

Thanks for the feedback. The ID should be computed from the name you choose. How did you create those projects? What's their name?

I created both projects via the UI, but I've been using Cospend for a long time already.
One of the two projects that I created and didn't touch for a long time has a last_changed of 2020-04-07T20:01:59.000Z.

v4.1.3 is being built right now. It will be available in an hour or so. Could you revert your local change, update to v4.1.3 and confirm if it fixes your issue?

I'm still curious to know the project names. I'm assuming you chose a numerical project name which produced numerical IDs as well. But maybe an older version of Cospend produced these IDs, even with a non-numerical name...

Thanks @julien-nc
The update fixes this problem.

Regarding the project names. The names are not numerical. Both project names look like /
In both projects I track expenses between people. The name don't even include a number
