MinimServer, booklet and BubbleUPnP Server

[meisbedi]

Im using a combination of MinimServer, my own Control Point and BubbleUPnP Server as an Open Home Renderer. After I activated the booklet feature, I noticed, that all the tracks, that had booklet information inside the metadata did not play with BubbleUPnP Server anymore. BubbleUPnP Server reports the http error code "500: Internal Server Error".
I'm using the following setting in tagFormat: Comment.displayFormat={$*infoFileURI^<a href="^"></a>$comment^^^/ }.
I checked the metadata, that are sent by Minimserver, and they are correct.
I also cross checked the behavior with the Lumin App, and I can replicate the problem.
If I control my renderer (PS Audio bridge II) directly, bypassing BubbleUPNP Server, the file plays without a problem.
As a workaround, I remove the information related to the booklet link, and all the files are playing again.

Hopefully, this helps anybody else experiencing similar issues to understand what is going on, until a fix is available for either MinimServer or BubbleUPnP Server.

Can you try the recommended tagFormat setting:

Comment.displayFormat={$*infoFileURI^<a href="^">Digital booklet</a>$comment}

Hi,
using the recommended tagFormat setting did not help. It added the name Digital booklet after the URI string.
But BubbleUPnP Server still reports the http error code 500.
I suspect that this behavior is caused by the fact, that the URI string is represented as a html escaped string within the metadata. This is what separates this information from the rest of the metadata.

Edit: replaced my previous response.

Is it HTML escaping or XML escaping? The latter seems more likely. Please post the exact contents of the Description metadata received by the control point when BubbleUPnP Server is involved.
