Microsoft Web API 5.2.7 causes issue with GetTreeNode and FormDataCollection

[bythewiseman]

This is an known issue at Umbraco HQ and was fixed. Please see:

https://github.com/umbraco/Umbraco-CMS/issues/3796

And is easily fixed in the FluidityTreeController.cs file by changing:

public TreeNode GetTreeNode(string id, FormDataCollection queryStrings)

to

public TreeNode GetTreeNode(string id)

and add this line at the start of the method:

var queryStrings = new FormDataCollection(Request.RequestUri.Query.TrimStart('?'));

I have branched and fixed locally. Can I help by pushing this fix to you somehow?

I am experiencing this issue as well on Umbraco 7.15.3. You get an error screen when you view an entry within a Fluidity section. Here's the error log entry:

Here's the error message from the failed request (it responds with an HTTP 415 code): "The request contains an entity body but no Content-Type header. The inferred media type 'application/octet-stream' is not supported for this resource."

I'm also happy to submit a pull request (though I note that the latest version of Fluidity was released well over a year ago, so not sure if it's being actively maintained).

If you have a PR that works, then perhaps submit regardless, so at least others can fix locally.

[Nicholas-Westby]

The above code changes would fix it locally. A PR would only be so the maintainers can easily merge it.

FYI, I have verified that the above-mentioned fix works. I created a local release of Fluidity so I don't have to wait for the maintainers to release a new version. If anybody wants it, here are the files (zipped):

local-nuget.zip

If you are familiar with how to install NuGet packages from a folder on your file system, this should work for you. It is just the develop branch with the code fix mentioned above by @bythewiseman.
