Cannot get geometry object from data you send to the GEOMETRY field

Attempting to export and import one of the databases for my omeka 2.6.1 instance. I am currently running mysql 5.1 and trying to import the database into mysql 8.0. I get the following error when I attempt the import. It appears to be associated with the Neatline Plugin.

ERROR 1416 (22003) at line 703: Cannot get geometry object from data you send to the GEOMETRY field.

I also tried to import the mysql dump into mysql 5.7 and got the very same error message.
Is there a fix available for this?

From the Neatline developers: other users have run into this problem, and we do not currently have a solution. There is some issue between versions of MySQL, we are currently working to find fix.

If you could provide us with any additional information, it would be helpful - importing using a .sql file or .csv file? using phpMyAdmin? If you could share a row of data that is causing the error message, that could also be useful, along with any other relevant details to your MySQL setup.

Thank you,
Elizabeth
