RSS Read node 404 when using variable reference but works when using string

[bbellini]

Describe the problem/error/question

The RSS node does not read the feed when I reference it as a variable, but when I paste in the URL to the feed, it reads it fine. I used the built-in parameter dragger and moved the RSS URL from the previous node into the URL field for the RSS Read node. It is returning the 404 error shown below. I tried stringifying it based on another post I saw here, but that didn’t work either. Let me know if there is anymore info I can provide to help, thank you!

Working when pasting the same string.

What is the error message (if any)?

Status code 404

Hey @bbellini,

Welcome to the community

Looking at the error message the issue is with the 5th item coming from Supabase, Can you double check that it has a value for rss_url and that it is valid. The 404 will mean that the URL can’t be found so it sounds like it is partially working it is likely to just be bad data.

In the other screenshot I shared, I can show the RSS URL working when putting in the raw text from the rss_url variable. I also upgraded to 1.55.3, but I am still getting an error.

Here is another screenshot using the debug node to print out the results from the rss_url, which are exactly what you would expect. However, when feeding the URL to the RSS Read node, I still get the same error.
