Hello everyone.

We have decided to phase out the Mixed Reality Forums over the next few months in favor of other ways to connect with us.

The first way we want to connect with you is our mixed reality developer program, which you can sign up for at https://aka.ms/IWantMR.

The plan between now and the beginning of May is to clean up old, unanswered questions that are no longer relevant. The forums will remain open and usable.

On May 1st we will be locking the forums to new posts and replies. They will remain available for another three months for the purposes of searching them, and then they will be closed altogether on August 1st.

So, where does that leave our awesome community to ask questions? Well, there are a few places we want to engage with you. For technical questions, please use Stack Overflow, and tag your questions using either hololens or windows-mixed-reality. If you want to join in discussions, please do so in the HoloDevelopers Slack, which you can join by going to https://aka.ms/holodevelopers. And always feel free to hit us up on Twitter @MxdRealityDev.

Failed to upload file Error [Object, Object] - In device portal

This is a very strange problem, when I am trying to upload the file to HoloLens through device portal, I get this error. I searched this forum and found out that for some people it is happening in Edge browser, for others in Firefox. For me unfortunately it is happening in all browsers (Edge, Chrome, Firefox)
I can rename the file, save the file, also delete the file, but cannot upload a file! This is driving me crazy, because it is important for scenario to upload a configuration file to the local storage. From which the application reads settings.
I tried running Fiddler in the background and found out that I am getting HTTP 429 response, citing too many request!

  • The same thing happened to me also today. I am also having trouble to install apps directly from Visual Studio, and I have to create app packages and install them via web browser. Does it have something to do with the Hololens software version? Mine is release.170917-1700

  • Check out my response here, it looks like Chrome 62 doesn't send the content-type header due to the way that MS's JavaScript constructs the request. I diff'd a working and non-working example and the content-type header is the only difference I could find.

  • What doublerebel said.
    tl/dr - use IE.
