Importing Translated Boolean Immediately gives a System.NullReferenceException

[StevenDeBacker]

When I try to import translations for booleans, the import process immediately stops and gives this error:

Importing attributes, picklists work well.

I just made a test with a boolean and it did not fail.
Would it be possible to get your Excel file (even with just a faulty boolean)?

I found out what the error gave.
One of the boolean values (of the default language) was overwritten via the maker portal.
So instead of yes/no there was another value. This value accidentally started with a space character.
I did not change it in Excel.
When importing, the import fails.
If I removed the line withe the trailing space, the import went well

I will check if I can add some check to avoid/remove trailing space

But thanks for finding the issue
