Describe the bug
A clear and concise description of what the bug is.

To Reproduce
Steps to reproduce the behavior:

1. tumblr is redirecting some tag urls to search urls, it seems more frequent with non-ASCII tags, but not consistent, they may be A/B testing.
2. make any tag search
3. if it doesn't redirect, replace "tagged" in the url with "search" to get the url
4. app will fail to download
5. logs contain:
   TumblrSearchCrawler.CrawlPageAsync: Microsoft.CSharp.RuntimeBinder.RuntimeBinderException: 'System.Dynamic.ExpandoObject' does not contain a definition for 'searchApiResponse'
   at CallSite.Target(Closure , CallSite , Object )
   at TumblThree.Applications.Crawler.TumblrSearchCrawler.d__13.MoveNext() in C:\projects\Tumblthree\src\TumblThree\TumblThree.Applications\Crawler\TumblrSearchCrawler.cs:line 127
   because it's a different API

Desktop (please complete the following information):

• TumblThree version: v2.14.2
• OS: Windows 11
• Browser: Firefox
• Version 129

I'm not sure what you expect.
Some tags cannot be searched for even though they are used and assigned to posts. That's a glitch on their side. The most obvious sign for a "broken tag" is the redirect (in the browser) from tag search to normal search, as you have also experienced.

I am not sure if the person who started this thread meant this but try to download the following link. It works in a webbrowser but not in TumblThree:

https://www.tumblr.com/tagged/ai%20girl

[ErikBrown2]

And this one is reported offline by TumblThree while it works in a webbrowser:

https://www.tumblr.com/tagged/sexy%20ai%20generated%20art

Update: This one worked after restarting TumblThree and trying it again.

Both work in TumblThree 2.14.2 and 2.15.0 (if the login succeeded resp. still logged in).

https://www.tumblr.com/tagged/ai%20girl does not work for me. I have tried it on three PCs and the behavior is the same on all three. When I queue the blog and then start download, then within one second the blog disappears from the queue and nothing is downloaded. I have tried it also with the setting "Advanced - Use new mode of handling Tumblr authorization errors" but this makes no difference. And yes, I have made sure that TumblThree was still logged on to Tumblr. (that was indeed my mistake with the other URL)

Since it works for you, there must be a difference between our setups that causes it not to work for me. Can you suggest anything that I can try?

[thomas694]

It was nothing special, just a clean installation (unzipped to new folder and old settings folder removed) for testing.

[mjharwood]

It worked for more cases after I upgraded to 2.15.0, but one case that worked stopped working again. Tumblr is just borked sometimes.

You could try logging out of tumblr and back in again. That might help convince tumblr to change which a/b group you are in.

Since https://www.tumblr.com/tagged/ai%20girl works for you but not on any of my three PCs, I have borrowed another PC, re-installed Windows 10 and TumblThree on it. I have kept all settings of TumblThree as original. But also on this PC https://www.tumblr.com/tagged/ai%20girl does not work. When I queue the blog for download and start the download, then within a second or so the blog is removed from the queue and nothing is downloaded from it.

I have attached the log here.
