'RedisCheckpoint' object has no attribute 'serde' Running Migration Tool

[yakphi]

Running the actual last version of opengpt using docker compose.
One terminal for the backend and frontend and another the migration tool.

It throws the following error:

I tried to use older versions of docker opengpt images but I got different errors also migration checkpoints.

Thanks in advance for any help.

Solved updating the docker opengpt image of the migration tool Dockerfile to this: 'dd4b9f7'

It seems there were changes in langgraph that affects the migration.

Also I had to start with an empty posgress db as there is migration that add a foreign key to user that is not compatible with the migration tool.
