    Error on uploading images to S3


    I have followed all the threads under this topic but just can't get this extension to work for uploading images on S3. I have used the AWS CLI to check if the objects can be written with the access key and secret key and that seems to work fine.

    The version of Umbraco is 7.2.8, I have uploaded the AST package, set the keys and have set awsSaveMediaToS3 to true. Have also installed the AWSSDK.S3 nuget package on the project.

    I don't see any errors in the App_Data/Logs and the only error I get is on the browser console with a 500 on POST http://localhost:7606/umbraco/backoffice/UmbracoApi/Media/PostAddFile?origin=blueimp 500 (Internal Server Error)

    Would be great if you could give me some pointers.

    I'm also experiencing this issue. Not sure if this is an Umbraco core issue or an issue related to AST Amazon S3 package. I've seen a lot of posts regarding this issue, not specific to AST Amazon S3 package, but thought I would raise it here to be sure.

    I'm running Umbraco 7.3.1, getting the same 500 error in Chrome, however I'm seeing the following error in Umbraco logs:

    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)
