AttributeError: 'exceptions.AttributeError' object has no attribute 'code'

What steps can be taken to reproduce the issue?

New CKAN site,

8 organizations

1st data set added with a simple JSON file

[saper]

I have disabled all multilingual plugins as a workaround.

[torfsen]

I don't know about the first traceback (AttributeError: '_Globals' object has no attribute 'fields'), but the second issue (AttributeError: 'exceptions.AttributeError' object has no attribute 'code') has already been fixed in 396973e. That fix hasn't been released, yet, however.

[saper]

Thanks @torfsen - yes, I had a look at it and considered it merely a mild annoyance, didn't even bother to file it. Thanks for fixing it so quickly.

[jeverling]

I see the first error you mention, AttributeError: '_Globals' object has no attribute 'fields', only when I have the hierarchy extension enabled, specifically the error doesn't appear when I disable hierarchy_display. This problem didn't exist in 2.7.2 which I was using before.
Do you use this extension by any change?

[jeverling]

There is an open issue on ckanext-hierarchy: ckan/ckanext-hierarchy#25

It works for me when installing the fork. Your problem might have been unrelated but at least I saw exactly the same error message.

[saper]

@jeverling nope, I don't have hierarchy extension installed, it was coming only with multilingual extension.

[pdelboca]

Closing this as Flask Migration has been completed.
