- Exception message and stack trace:
- Steps to reproduce the issue:"
We use the upload functionality with MVC and we generated clientproxy due to a bug in ABP. When we upload a file, the contentlength is 0 when we reach the generated clientproxy.
Contorller
Upload method in generated proxy
<br>
In the AppService the contentlength is also 0
What is going wrong with this upload? This worked in an older version of ABP without the generated proxy.
Thanks.

There is a breaking change regarding using
IRemoteContentStreamin version5.0.0. It seems to me that the object is probably disposed of while you call Uploadref: https://github.com/abpframework/abp/pull/9180
But it would be great if you could test this to speak beyond the assumptions. For this, you can pass false to disposeStream parameter while creating an instance of
RemoteStreamContent.new RemoteStreamContent(...., disposeStream: false)If it is as I said, I believe you can solve the problem similar to the code below:
await using var memoryStream = new MemoryStream(); if (Organization.ProfilePictureFile != null && Organization.ProfilePictureFile.Length > 0) { await Organization.ProfilePictureFile.CopyToAsync(memoryStream); memoryStream.Position = 0; createOrganizationDto.ProfilePictureStreamContent = new RemoteStreamContent(memoryStream, fileName: Organization.ProfilePictureFile.FileName, contentType: Organization.ProfilePictureFile.ContentType); } var organization = await _organizationAppService.CreateAsync(createOrganizationDto); await memoryStream.DisposeAsync();ref: https://github.com/abpframework/eventhub/blob/f95fda41dbd821c905ed6c675e946a86fb91a6fa/src/EventHub.Web/Pages/Organizations/New.cshtml.cs#L42-L52
