Updating a Record Causes an error

[kevinreiss]

Expected behavior

When you edit a DSS record you can save your chance.

Actual behavior

Visit https://dss.princeton.edu/resources/6532/edit, when you save the record you get the standard load balancer error screen.

Steps to replicate

1. Log in to DSS
2. Visit https://dss.princeton.edu/resources/6532/edit
3. Make an edit
4. Hit Update Resource
5. You will receive a 502 Bad Gateway error and see the load balancer error screen.

Impact of this bug

Can't edit this specific record.

Acceptance criteria

• Editing this existing record works.

Implementation notes, if any

I can't find any honeybadger errors about this so maybe a load balancer issue? Also creating new records seems to work fine (I was able to create a new one and delete it without any issues).

Other large records can update fine. Tunneling into a DSS box directly and updating the record can also update fine.

@kevinreiss first you need to login. Then you can edit.

The edit path works but you cannot update.
