Please fill in the following fields:

Pre-built SDK from the website or open-source from this repo: Website
Firebase C++ SDK version: 6.15.0
Firebase plugins in use (Auth, Database, etc.): Storage, Auth, Firestore
Additional SDKs you are using (Facebook, AdMob, etc.): N/A
Platform you are using the C++ SDK on (Mac, Windows, or Linux): Mac
Platform you are targeting (iOS, Android, and/or desktop): iOS and desktop

Please describe the issue here:

(Please list the full steps to reproduce the issue. Include device logs, Unity logs, and stack traces if available.)

Try and upload a file using fileRef.PutFile( localPath ).OnCompletion( .... ) results in "No object exists at the desired reference" on iOS, works on Mac desktop. There's also a log warning of "CFURLResourceIsReachable failed because it was passed an URL which has no scheme" directly before hand. The local filename is absolute and readable. PutBytes works fine.

It's not a permission error on either the local file or firebase storage location since it works fine if I load the file myself into a buffer and use PutBytes.

GetFile doesn't work either, I have to load into a buffer with GetBytes and save out myself. This isn't ideal because I first need to find out the required buffer size with GetMetadata, resulting in a two step process.

Please answer the following, if applicable:

Have you been able to reproduce this issue with just the Firebase C++ quickstarts ?

No. GetFile and PutFile are not used in the quickstart, only GetBytes/PutBytes which work fine.

What's the issue repro rate? (eg 100%, 1/5 etc)

100%.

How did you format your localPath?

"The source of the upload. This should be a file system URI representing the path the object should be uploaded from."

Hope this helps!

It was previously using a pure absolute path. I've tested and can confirm adding "file://" in front of this works. It previously worked on mac desktop fine without, but my desktop builds are currently broken so I can check that it still works with. Will adding "file://" still work on desktop and when I port to Android?

[mark-grimes]

I've tested on Mac desktop and it does indeed work with "file://". So my only question is whether this is compatible with Android? I don't have an easy way of testing, our Android app is distant on the roadmap but we would want any code to work with that too.

According to Android API Doc, it can be file:// or content://

Thanks. Closing, as it was my incorrect use of the API.
