Error when creating share

[DJ-3ncoder]

I am using nextcloud snap but the the people on the snap-respository told me that such issues affect the server-repository.

I have been getting this error for a few days now:

When I want to share a folder with another person on my nextcloud there is this error:

Translation: "Error when creating share"

How to reproduce this error:
Click on the sharing-icon on the folder and select another cloud-user.
Then the error message appears.
Despite the error the user gets access and the user is shown in the sharing-list after refreshing the page.

Tested on version 18.0.4
This has only started occuring recently (snap updates itself)

I get this in v19.0.0 and v19.0.1 (upgraded from v18 to v19, worked fine in v18).

Created new file using web interface, clicked share.
Error message appears: Error creating the share.

File manager shows (for a short while) that the file is shared,
and activity log shows share link was created (and expired),
the share details don't show link.

The log:

Issue only occur after enabling :
Settings > Sharing > Allow Users to share via link > Set default expiration date for link shares

[wivaku]

To be sure, the summary is: sharing with expiration date does not work.
when I set expiration date (either default or for specific share): I get error message and can not share.
When I share without expiration date everything is fine.

What further triage is needed? Happy to help.

I have added the linked issue above with more details from the browsers JavaScript log.
For me the message also appears when Settings > Sharing > Allow Users to share via link > Set default expiration date for link shares is not enabled

Pretty sure the server error is the indication of what the root cause is.
It seems the expire date is a boolean instead of string, which causes the format() of that string to fail.

I also get the error in Nextcloud 19.4. I share it with users and groups, not as a link.
There is no entry in the error logs.
The checkbox with expiration date i not checked, but doubt it's relevant as I not share it via link.

[wivaku]

do you have a default expiration date set?
Settings > Sharing
Either for "Set default expiration date for shares" or "Set default expiration date for link shares"

[Skalli]

I tried any combination, but no change. I tried setting the share on a folder. It works when sharing a file.

[wivaku]

so do you get ther error when both settings are disabled?
Could be a different issue then.

What do you see in the server log?

[Skalli]

I get the error no matter what this setting is for either: All disabled, one of them enabled and all of them disabled, can't share the folder.
Server log doesn't show anything about the error to share.
