Non-negative number error connecting to SugarCRM MySQL

Dear all,

i'm getting this error while connecting to a Sugarcrm mysql database (mysql 5.7 Charset: utf8mb4 Collation: utf8mb4_general_ci)

, not on all the tables but in most of them. Anybody has ever experienced this? i dont have any useful information from the error log

I have tried with latest release of powerbi, and a previous one, but still the same error

If it really has to do with some field identified as numeric while it is not? How do i skip this check in case?

Thanks a lot!
