panic: runtime error: index out of range [0] with length 0

[intel352]

I'm moving from golang-migrate to Atlas. I missed that Atlas doesn't also use .down files, so working with an existing migrations directory resulted in the .down being processed first, and then a runtime panic.
Knowing about this, hopefully you can detect/mitigate the error so that it can at least be helpful regarding the cause.

Contents of the atlas_schema_revisions table:

20250124201454,create_affiliate_table.down,2,1,1,2025-02-03 14:23:17.650914 +00:00,812417,"","",eBwwb9odmRgSXp04uafjCfoCupCSaCE8QL+dwqil4NE=,null,Atlas CLI v0.30.1-c0d486a-canary

Cmd panic

atlas migrate apply --env=local

Hey @intel352 👋

Did you set the migration.format to golang-migrate?

env "local" {
  ...
  migration {
    dir    = "file://migrations"
    format = golang-migrate
  }
}

[intel352]

I did actually.

Can you share your atlas.hcl file?

[intel352]

At the time, it looked like this:

variable "url" {
  type = string
  default = ""
}

env "local" {
  // Define the URL of the database which is managed
  // in this environment.
  url = "postgres://scrubbed"

  // Define the URL of the Dev Database for this environment
  // See: https://atlasgo.io/concepts/dev-database
  dev = "docker://postgres/16/dev?search_path=public"

  migration {
    // URL where the migration directory resides.
    dir = "file://migrations"
    format = "golang-migrate"
  }
}

Config looks OK, can you please provide a simple directory example that reproduces this issue?
