API - queueAlbum: TypeError: argument of type 'NoneType' is not iterable

[josevh]

Excuse me if known issue or duplicate, found some bugs reported that are similar but not the same.

Writing program which requires on API call to queueAlbum.
Example call:

http://{IP}:{PORT}/api?apikey={API_KEY}&cmd=queueAlbum&id=d924cd74-09be-3611-8816-bd4d4fc73049&lossless=False

The API call returns the following error:

500 Internal Server Error

The server encountered an unexpected condition which prevented it from fulfilling the request.

Traceback (most recent call last):

On my 'Wanted' albums I get the following:

and

On the Headphones logs via site I get:

This has been tested with numerous albums.

Tested:

If you want to queue an album for download, it has to be in the database first. Off the top of my head I don't think there's an api call where you can download something right off the bat but it might be something I can look into

Hi rembo,

Thank you for taking the time to reply.

I played a little with the API and it seems that after adding the artist to the database (addArtist), Headphones fetches the albums. I also noticed that Headphones uses the album's 'rgid' and not the 'albumid' and now queueAlbum works after adding the artist. I will probably still check to make sure that the album is added.

I'll keep experimenting but thank you for solving the problem, appreciate it.
