Storage Firebase, bad request 400 for GetDownloadUrlAsync

[jendoubi med aymen]

I'm trying to get a download URL for a file but I have an exception, i use FirebaseAuthentication.net and FirebaseStorage.net in a VSTO Powerpoint project.

var url = await firebaseStorage.Child("parent").Child("filename").GetDownloadUrlAsync();

GetDownloadUrlAsync() throws an exception
Exception occured while processing the request. Url: https://firebasestorage.googleapis.com/v0/b/Your-bucket.appspot.com/o/parent/filename bad request Response: { "error": { "code": 400, "message": "Invalid HTTP method/URL pair." } }

In a WPF or winform project the function works very well and I can make HTTP calls even with WebClient or RestClient but in a VSTO project always I have the same error Bad request: 400

i have this problem too , does anyone solve this?

Can you try using fiddler to sniff the traffic? Perhaps VSTO is changing the request somehow?
