When creating a mapping, the form allows for a mapping ID/machine name up to 255 characters in length. But, when creating a mapped object, which references a mapping by ID/machine-name, the salesforce_mapping field in the DB only accepts a maximum of 32 characters.
So, if your mapping's machine name/ID is over 32-characters in length, you cannot save Mapped Objects for data it pulls down, due to a "Data too long for column 'salesforce_mapping'" error on MO save.
OR
Drop the max-length of the salesforce mapping ID/machine name to 32-characters.

It's likely this issue predates Contrib.social: some issue and comment data are missing.
Just in case anyone is still seeing this, I noticed the same error message in my logs recently. Apparently in my case, the issue is that I have a single Webform submission that creates multiple SF records. On return, only one SF record can be mapped to the Webform submission. The error doesn't seem to have any effect on the actual SF records creation.
