This is happening to me as well. On Azure, as a Web App. Local development environment with the same code works fine.

Investigations are ongoing.

Hi

Yes, don't use 7.3.0, he'll fix it but he's gone on holiday. So, make sure you use:

Upgrade-Pacakge UmbracoCms -Version 7.2.8

Grazitti

I'm seeing the same error in 7.4.1. Will see if an issue has been raised.

Regards

I am getting this error in Umbraco version 7.4.1 assembly: 1.0.5891.23238 also

    2016-05-20 10:53:12,725 [P8052/D15/T552] ERROR Umbraco.Web.WebApi.Filters.FileUploadCleanupFilterAttribute - Could not acquire actionExecutedContext.Response.Content
System.NullReferenceException: Object reference not set to an instance of an object.
   at Umbraco.Web.WebApi.Filters.FileUploadCleanupFilterAttribute.OnActionExecuted(HttpActionExecutedContext actionExecutedContext)

Any ideas? Only seems to happen with files over 34mb in size!? This is on our dev environment using IIS express. The process on the live server when published is fine.

Have you removed the Size property (alias umbracoBytes) from the media type?

I got the same error when I removed that field when trying to solve OutOfMemory exceptions for large file uploads (see U4-6809)

HTH

Ver

 <system.web>
<httpRuntime requestValidationMode="2.0" enableVersionHeader="false" maxRequestLength="204800" executionTimeout="99999" />
</system.web>

I removed the following attribute to get this working from the httpRuntime node in web.config

fcnMode="Single"

and added the following based on other users suggestions

maxRequestLength="204800" executionTimeout="99999" targetFramework="4.5"

Anyone got a solution for this one? It's really frustrating for our client..

"upvote"

Hi all, I am too stuck at same place. Can anyone please post a solution if there is one!!

I am getting the same error. Can someone please take a look?

I am using Umbraco version 7.4.3 assembly: 1.0.5948.18141 , get error

Umbraco.Web.WebApi.Filters.FileUploadCleanupFilterAttribute.OnActionExecuted

while uploading image

Please Help me out.

Still an issue on 7.5.11 .. Same error as Mukund

ERROR Umbraco.Web.WebApi.Filters.FileUploadCleanupFilterAttribute - Could not acquire actionExecutedContext.Response.Content System.NullReferenceException: Object reference not set to an instance of an object. at Umbraco.Web.WebApi.Filters.FileUploadCleanupFilterAttribute.OnActionExecuted(HttpActionExecutedContext actionExecutedContext)

I tried this on another client's site that is still at 7.2.4 and it worked fine.

Things I've tried -

• fcnMode I have tried all enums
• maxRequestLength, executionTimeout, maxAllowedContentLength
• ImageProcessor configs maxwidth/maxheight on Resize plugin

Has anyone solved this? Told the client to resize all their images manually before uploading to Umbraco. Sometimes that works lol

Would it be worth trying to downgrade ImageProcessor back to the one that worked ?

We were having the same issue with 7.5.11 and it turned out to be an issue with access restrictions on the media folder. Needed to give write permissions to the IUSR account.

I just had this same problem and found that the Media file had changed permissions and just had read for IIS_Users. Once it had write access i could upload again

Same issue here. Using v7.6.3

Weird thing. Using this same property editor (MediaPicker2) with a different custom property editor only different size variations and no problems...

EDIT:

I went back and deleted the media type, copied the the other, changed the cropper to the specific one I needed and that worked.

Has anyone found the source to this issue? I've got the same thing on a clients site running Umbraco 7.2.2, can't use the 'Click to Upload' option (same error message as posted here) but can right click, add a file then upload the media that way.

I was having this issue for an Azure installation, where I could not upload images (ERROR Umbraco.Web.WebApi.Filters.FileUploadCleanupFilterAttribute - Could not acquire actionExecutedContext.Response.Content) and images did not display properly. In my case I had forgotten to add the UmbracoFileSystemProviders.Azure NuGet package

i got this error also on umbraco 8 and for me was a permssion issue on the media folder
