mysql failed connecting to MS Access - mysql

Question

I'm trying to transfer my database from Microsoft Access to MySQL (I'm using MySQL workbench). for that I need to connect MySQL to Access but I'm facing some problems.
I'm following these guidelines:
https://dev.mysql.com/doc/workbench/en/wb-migration-database-access.html
when testing the connection it shows this error message:
Unhandled exception: grt.Dict key must be string.
I checked the log for more information and this is what I found :
Starting...

- Connecting to source...
Connecting to ...
Opening ODBC connection to DSN=northwind...
Traceback (most recent call last):

ERROR: Error during Connect to source DBMS: 'grt.Dict key must be a string'
ERROR: Exception in task 'Connect to source DBMS': KeyError('grt.Dict key must be a string',)
Failed
It seems that I need to make some changes in the files but I don't have any idea how to do that and I couldn't find answers to that online.

Answer 1

Hello this is late [very]. The solution that worked for me was making sure during adding a DSN (Data Source Name) you added your database [as in the ms access file]

Answer 2

You see this error if you're trying to migrate data from an old-format database (Access < 2010 .mdb file) using a newer ODBC connector. First save the file in a more recent format first (.accdb), and then try the migration again.
