Wizard Step 1: Editing Description results in Unexpected Error

[mariobehling]

When the user tries to edit the "Description" area in step 1 of the wizard an "Unexpected Error" appears. If the user refreshes the wizard and copy/pastes the info it works, but initially it always shows the error.

@iamareebjamal Same error which was shown in case for Private Events.

Also here are the relationships getting sent by frontend https://github.com/fossasia/open-event-frontend/blob/development/app/serializers/event.js

[iamareebjamal]

Yes, will fix this today on server as a workaround but it needs to be fixed in frontend mainly

[iamareebjamal]

See if removing those 2 relationships does not break anything and fixes the issue because they are computed relationships, not real

@iamareebjamal It is working after removing the orderStatistics Relationship. Also eventGeneralStatistic should not be removed as all the event statistics like Speakers, Session are coming through this relationship. I will take a look if we are using orderStatistics anywhere else in FE, if no I will make the PR for the fix.

[iamareebjamal]

They should work even after removing manual linking. I'm not asking to remove if they are not used. I'm asking to remove knowing that they are used
