Project import fails when imported project contains a user with a different login but identical email to an existing user on the instance.
'Error while processing import, please contact your Mingle administrator. Undefined method 'ancestors' for nil.NilClass'
Some instances where this bug will manifest:
- After successfully backing up our project from our eval version, we attempt to import the project into our hosted version and we get the above error message.
- Project loads into my local instance but won’t load to the hosted instance
There is a username in the project being imported that is different from the username in the existing mingle instance but both have same email id.
Unzip project export
update users0.yml to have the same login name as that which already exists in Mingle instance. Use email address to lookup.
zip the project into a new file and import
