aerich init-db with sqlite3 freezes

[massiccio]

Hello,

I have been observing the same behavior reported at here while using aerich with sqlite
I have no problem when using the same models with postgres.

aerich init -s src/ -t tci.sqlite.database.TORTOISE_ORM
Success create migrate location ./migrations
Success write config to pyproject.toml

aerich init-db
Success create app migrate location migrations/models
Success generate schema for app "models"

I have tried the workaround described here, i.e., downgrading to version 0.6.3.
That fixed the init-db, however the upgrade still fails.

I have also tried not to have that column as an index, and in spite of the migration throwing an error, the upgrade succeeded

Try remove migratetions/models and aerich table and rerun migrate

[massiccio]

I tried that, but to no avail.

Just in case you wish to reproduce the problem, here is a simple model.

class Alert(models.Model):
    id = fields.IntField(pk=True)
    opsgenie_id = fields.CharField(max_length=50, index=True, unique=True, null=False)
    priority = fields.SmallIntField(null=False, index=True)
    message = fields.TextField(null=False)
    team = fields.CharField(max_length=20, null=False)
    site = fields.CharField(max_length=10, null=False)
    stage = fields.CharField(max_length=3, null=False)
    created_at = fields.DatetimeField(null=True)
    updated_at = fields.DatetimeField(null=True)
    jira_id = fields.CharField(max_length=30)
    acknowledged = fields.BooleanField(default=False, index=True, null=False)  # try to remove this field

orm_config = {
        "connections": {
            "default": {
                "engine": "tortoise.backends.sqlite",
                "credentials": {"file_path": "db.sqlite3"},
            }
        },
        "apps": {
            "models": {
                "models": ["tci.sqlite.models", "aerich.models"],
                "default_connection": "default",
            }
        },
    }

Same happened to me.
It'd be great if someone can provide any sort of workaround.
