Hey there.
Currently trying my hands on a WS Script for [fanart.tv](http://fanart.tv). So far I've been able to get the data from the API to load (yay), but I'm not sure if I'm doing it right. There is no output when I use json\_object, so I don't know if it accessed it, since it also doesn't error out when it _doesn't_ find an object by that name.
But first, here's the current code:
```
# ###################################################################

debug "on" "C:\Users\Tarulia\AppData\Roaming\Mp3tag\debug_fanarttv.txt" "5"

# API returns 404 on error, no need to read out error message as Mp3tag errors out on 404
# get the actual image
json_select_object "albums"
json_select_object "8f4d4f05-36ed-3c81-86a7-aae2a03b1520"
json_select_array "albumcover" 0
json_select "url"
outputto "coverurl"
sayrest
```
And the Debug Output (note that I commented out the select\_array and following, see below)
```

```
Note that I hardcoded the second json\_select\_object for testing.
Now I have multiple problems:
**1.** When I use ParserScriptAlbum instead of ParserScriptIndex, no log file is created. At all. Also I have no idea what's the difference really, but I assume I actually need the ParserScriptAlbum since it's probably showing the result of the selected album?
**2.** When I use the script like that, there is no log file created, at all, unless I comment out the json\_select\_array and the following lines.
**3.** In the real world I can't actually hardcode the MBID into the json\_select\_object function, but I haven't been able to use the actual ID in any way. I tried using %MUSICBRAINZ RELEASE GROUP ID% and %s both with and without quotes, but according to the debug output the value isn't used. Is there even a way of using that variable? If not, well.. I got a problem 🙂 Can I use json\_foreach on the albums object or does it not work on objects, but only on arrays?
**4.** Is it normal that there is no Output when selecting an object? I have no idea if the selection actually works or not. Is there a way to get a serialized version of the selected object into the output?
Hope someone can give me a hint and/or get me on the right track from where I can continue on my own 🙂
Thanks in advance
