Your challenge_group.avatar or changed value in UserTeam1Web.Controllers.ChallengeGroupController.delete/2 (I don’t know your code) as in stacktrace contains map with file_name and updated_at keys. Both Arc.Actions.Store.store/2 and Arc.Actions.Url.url/2 requires to have valid parameter for Arc.File.new/1 which are one of:

  1. Remote url - i.e. binary which starts with http
  2. Local url - i.e. any other binary like /path/to/file.extension or relational file path like: ./path/to/file.extension
  3. Map which contains both of two keys: binary and filename
  4. Map which contains both of two keys: filename and path

This means that if you pass map or struct with:

  1. only one of those keys: binary, filename and path then it will fail
  2. all of those keys: binary, filename and path then path key would be ignored

I don’t know your code and structs, so I can’t say what you can pass, because from this part of error:

(arc) lib/arc/file.ex:16: Arc.File.new(%{file_name: “PICTURETEST.png”, updated_at: ~N[2018-10-24 16:15:58]})

I can see that you are passing only file_name and updated_at, so what you need to do is:

  1. Use file_name and pass it in remote url
    like: http://my.domain/path/to/#{challenge_group.avatar.file_name}

  2. Use file_name and pass it in local url
    like: /path/to/#{challenge_group.avatar.file_nam}
    or:   ./path/to/#{challenge_group.avatar.file_name}

  3. Use File.read/1 or File.read!/1 to get content of file and pass it in binary key, remove not needed updated_at key and change key file_name to filename

  4. Get path to file you are trying to reference with file_name, remove not needed updated_at key and change key file_name to filename
