Hi @RPATARIN ,

Do you have the app Maps enabled on your server? I had the same issue which you describe here and opened an issue on Github for that:

It turned out, that the app “Maps” was interfering with the sharing API and caused the error message.
There is a fix already and it should be shipped with the next release of the Maps app:

Until then, you can avoid these issues by disabling Maps.

If you use federated shares, I would like to make you aware of this issue as well:

Hi Schmu

No, the Map application is not installed on the Nextcloud server.

Hm, strange. Looked very much alike.
Can you then please share more entries from the nextcloud.log, shortly after you tried to create another share.
In addition, please provide the output from the browser console. There is probably an error and the HTTP code 404.

A list of enabled apps would be nice as well.
There is an app for Nextcloud “issue template” which helps to collect the list of enabled apps and a lot of other stuff.

My problem is still relevant

Error in Chrome

This error in the browser console is the same which I had. So it looks very much the same like my issue with the apps Maps. While you don’t have the Maps app enabled, maybe another app is also causing this issue.

Can you please provide more entries from your nextcloud.log?

Maybe you can compare the enabled apps on my server with the enabled apps on your server and for testing purposes disable all apps, which you have enabled and I don’t.

Not wanting to hijack the thread but i also have this issue, though i hope this additional information helps someone figure out the problem.

I do not have the MAPS plugin installed, i CAN invite another user by email if they are on the same domain, but i cannot invite an external user, i get the following error in the logs

Swift_TransportException: Expected response code 354 but got code “554”, with message "554 5.5.1 Error: no valid recipients "

it doesn’t matter what external domain or email i use, i also cannot register new guests for the same reason, it will not invite them as it fails to send the email.

The share creation seems to fail if the email is not able to be sent.

Creating a guest account gives the following error;

An error occured during the request. Unable to proceed.
Sending email failed

(there are also 2 r’s in occurred, this should be easy to fix)

But also logs the same as above;

Swift_TransportException: Expected response code 354 but got code “554”, with message "554 5.5.1 Error: no valid recipients "

Hello, I had the same issue; have you configured your email settings correctly, so that Nextcloud can send emails at all?

Same here. Mailsserver is set up and working.
