[Bug]: Issue Parsing RSS Feed

[tomershvueli]

Describe the issue

Starting maybe a week or 2 ago I've had a podcast feed of mine not be able to pull in any new shows. Logs look like this:

Not sure what's wrong here but would appreciate any help in looking into this!

Steps to reproduce the issue

1. See code snippets above for parsing issue.

Audiobookshelf version

2.6.0

How are you running audiobookshelf?

Other

[nichwall]

Is this during an automatic download or when you're manually searching for episodes to download? Does it work for either or are both broken?

[tomershvueli]

@nichwall both. I first noticed that after a few days I wasn't seeing the pods I was expecting to in my feed. Then when I try to manually fetch new pods, I get an error:

[advplyr]

This is unusual in that the RSS feed is returning a JSON response when no request headers were set. I wasn't actually able to reproduce this in Postman but when I logged the response we were getting from axios it was JSON.
I added Accept: application/rss+xml request header and it is working now

[tomershvueli]

Thanks for your prompt responses and action on this issue! I'm looking forward to the next release!

[advplyr]

Fixed in v2.7.0

[tomershvueli]

Confirmed fixed!
