An error has occurred while saving dataAttempt to de-reference a null object---117

Installed Custom Metadata loader v 2.7 in sandbox.
Trying to upload Custom metadata records, after choosing csv file the screen is saying 'The CSV file contains 9 records.'.
After clicking Save the error is returned: 'Error: An error has occurred while saving data Attempt to de-reference a null object---117 '
Please help

I'm receiving the same error:

"An error has occurred while saving dataAttempt to de-reference a null object---116"

@nellymorozova did you ever find a solution for this? Thanks

@ahanson-cyber - no, I have not, tried different thing, but ended up using data loader
