Post Message property is longer than the maximum permitted length

1

I’am using the bulk import for migrating data from one Mattermost instance to another Mattermost instance.
When running this bulk import, I get the following error:
“Post Message property is longer than the maximum permitted length”

What solution can I use for this error?

I’am using Mattermost version 9.4.1
Database Schema Version: 117
Build Number: 7424719315
Database: postgres
