Return value of OCA\ContactsInteraction\Db\CardSearchDao::findExisting() must be of the type string or null, resource returned

👀 I'll have a look

[dehnhardt]

For some time now I do have the same Problem:

Me too, exactly the same error in nextcloud.log (above). Mail is received, on the other hand, but nextcloud mail app displays an error, and email is not stored into the sent mail folder.

Is more information required to solve this issue?

nginx:

[dehnhardt]

@kruthoff Is your database server PostgreSQL as well?

[kruthoff]

Yes. Postgres 11. Nextcloud 19.

[dehnhardt]

This seems to affect only Postgres users...

[hicwic]

same for me, but with the "share by email fonction". Email is sent, but an error popup, and the page is not refreshed.
