@kushthedude - Are you working on this?

@kushthedude @iamareebjamal - Is their a specific case for sessions to return duplicated data.?

For me, I have a user with two sessions which have been submitted but not accepted. But the api returns correct data.

http://127.0.0.1:5000/v1/users/2/sessions?sort=starts-at

By removing the filter also works fine for me.

I have given the API Link above it is returning same sessions for page 2
and 3. Same is the case on local

@codedsun Because there are not even enough items to do pagination, so obviously it'll return correct data

Ok will check it out.

Since the merged PR has been reverted. Reopening this issue, also please check https://github.com/fossasia/open-event-server/issues/6794 for reason why the PR was reverted .

I'll take a look at this.

@mrsaicharan1 #6794 was actual solution but it doesn't work with sort parameter, so that needs to be fixed

@iamareebjamal - If we change the queery to
query_.distinct(Session.id, Session.starts_at).join(User) it will work.

the error occurs because the Order by runs on different field and distinct runs on another one

Great, send a PR so we can revert it when ?order_by=ends_at crashes. That is not the solution

@iamareebjamal - Nopes this isn't the right solution. I am looking for more

Paste the SQL query generated in the statement with and without distinct
