ORM error with MySQL backend

[MattiaFailla]

Describe the bug

Hi Team, following the self-hosted docker-compose guide with MYSQL database the following error is issued:

fief-server_1  | WorkspaceDatabaseConnectionError: (pymysql.err.OperationalError) (1170, 
fief-server_1  | "BLOB/TEXT column 'message' used in key specification without a key length")
fief-server_1  | [SQL: CREATE INDEX ix_fief_audit_logs_message ON fief_audit_logs (message)]

To Reproduce

Steps to reproduce the behavior:

1. Create the docker-compose as in the tutorial
2. Configure the .env file with the data outputted after the configuration container (docker run -it --rm ghcr.io/fief-dev/fief:latest fief quickstart --docker)
3. Edit .env file and configure a mysql database
4. Execute docker-compose up

Expected behavior

Fief server should start and migration should be performed with a MySQL backend.

Configuration

• Cloud or self-hosted: self-hosted
• If self-hosted, Fief version: ghcr.io/fief-dev/fief:latest (sha256:31bba98a0d386a81ac5a5d4971904d8b1cedcb15c767c71f1ff5727cdc68db04)

Hail, @MattiaFailla 👋 Welcome to Fief's kingdom!

Our team will get back to you very soon to help.

In the meantime, take a minute to star our repository ⭐️

Farewell!

Hello @MattiaFailla 👋

Hmm, that's indeed an error during the creation of the database schema. It's strange because Fief is tested against MySQL during CI.

Could you tell me which version of MySQL you are using?

[MattiaFailla]

Hey @frankie567

I'm using MySQL Server 8.0.31-1.el8

Here is the docker-compose file:
(Please note that I've specified the 0.18 Fief-server version just for testing but this issue is present in every Fief version.)

version: '3'

services:
  db:
    image: mysql
    ports:
      - "0.0.0.0:3308:3306"
    env_file:
      - .env

  fief-server:
    image: ghcr.io/fief-dev/fief:0.18
    command: fief run-server --port 8585
    depends_on:
      - db
    expose:
      - 8585
    env_file:
      - .env

  fief-worker:
    image: ghcr.io/fief-dev/fief:latest
    command: fief run-worker -p 1 -t 1
    env_file:
      - .env

  redis:
    image: redis:alpine
    command: redis-server --save 60 1 --loglevel warning
    volumes:
      - redis-data:/data

volumes:
  redis-data:

And this is the .env

Hail, @MattiaFailla 👋

I've noticed you shared secret values: SECRET, FIEF_CLIENT_ID, FIEF_CLIENT_SECRET, ENCRYPTION_KEY. Those are highly sensitive and you should keep them secret.

For your security, I've taken the liberty to replace them with dummy values.

[frankie567]

Thank you for those details!

So it turns out it works with MariaDB, but not MySQL (🙄). I've added it to our CI so we can catch those errors earlier.

The culprit is actually an index on the message column of the AuditLog model. It's a TEXT column, so it's indeed a bit weird to have an index on this, don't really know why I did this.

I'll push a fix soon!
