I am getting the following stack trace from this section of code:

migrationRoot, _ := fs.Sub(migrationFiles, "/workspace/db/tern")

err = migrator.LoadMigrations(migrationRoot)

trace:
panic: runtime error: invalid memory address or nil pointer dereference

I verified in the container that there are tern migration sql files:

ck-55655549c4-vlbrr:/workspace/db/tern$ ls -al
