Bug report

Required System information

• Node.js version: 14.20.0
• NPM version: 6.14.17
• Source Strapi version: 3.6.8
• Target Strapi version: 4.3.6
• Source Database: sqlite or mysql (verified on both)
• Target Database: sqlite or mysql (verified on both)
• Operating system: Ubuntu 22.04 LTS
• Which script are you running: v3-sql-v4-sql

Describe the bug

The conditions values in the admin_permissions tables are improperly formatted after running the migration script, this causes application crashes for admin users assigned to any role created pre-migration besides the super admin.

Steps to reproduce the behavior

• create a quickstart v3 project
• add an admin user to the project, assign them the editor or author role
• create a quickstart v4 project
• migrate the database from v3 to v4 using the migration script configured for the sqlite databases
• start the v4 application
• log in to the dashboard as the created user
• dashboard will crash and 500 errors observed on the server side

Expected behavior

The dashboard does not crash and the server does not error.

I have created #40 to resolve this issue, it has been verified for both SQLite and MySQL/MariaDB databases. I have not tested it on a PostgreSQL database

Reopening this as I had to revert the PR merge of #40 as other users were reporting problems in #19
