Custom audience upload errors: INVALID and INVALID_PARAMETER


We’re getting this error message when attempting to upload an audience via our application:

When attempting to upload twitter_ids:
:message=>CustomAudience audience_identification_type can only be modified for Global Opt Out Lists", :attribute=>“audience_identification_type”

When attempting to upload hash email addresses:
:message=>“Expected valid file path, got “/ta_partner/xxxxxxxxxx/RBf0c53Iz1_W9m2.txt” for input_file_path”, :parameter=>“input_file_path”

We do not believe any changes have been made on our side since we have started to see this error. Our audience uploads were successfully completing as of late last week.

Is there any guidance you can provide on this problem?
