Firebase Storage Upload ErrorCode 40

[MalcolmnDEV]

Description

I am attempting to upload a zip file to Firebase storage. The zip file is located in the documents directory for my app.

I create the reference and use putFile to start the upload

`let storageReference = ORBFirestore.getStorage() .reference(withPath: "users/") .child("(userId)/(sensorZippedFolder.lastPathComponent)")

let uploadTask = storageReference.putFile(from: sensorZippedFolder, metadata: self.remoteStorageMetaData)`

Observing the progress I can see that it reaches 100% and then throws an error.

The error I receive looks like this:

Failed to upload zip to remote storage: FirebaseStorage.StorageError.unknown(message: "Unexpected 40 code from backend", serverError: ["NSErrorPeerAddressKey": <1c1e01bb 00000000 2a001450 400b0c02 00000000 0000005f 00000000>, "_NSURLErrorRelatedURLSessionTaskErrorKey": <__NSArrayI 0x10fe5e020>( BackgroundUploadTask .<1>, LocalUploadTask .<1> ) , "_kCFStreamErrorCodeKey": 40, "_NSURLErrorFailingURLSessionTaskErrorKey": BackgroundUploadTask .<1>, "_kCFStreamErrorDomainKey": 1, "ResponseErrorDomain": "NSPOSIXErrorDomain", "ResponseErrorCode": 40, "bucket": "orb-storage-01-dev-us", "NSUnderlyingError": Error Domain=NSPOSIXErrorDomain Code=40 "Message too long" UserInfo={_NSURLErrorFailingURLSessionTaskErrorKey=BackgroundUploadTask .<1>, _kCFStreamErrorDomainKey=1, NSErrorPeerAddressKey={length = 28, bytes = 0x1c1e01bb 00000000 2a001450 400b0c02 ... 0000005f 00000000 }, _kCFStreamErrorCodeKey=40, _NSURLErrorRelatedURLSessionTaskErrorKey=( "BackgroundUploadTask .<1>", "LocalUploadTask .<1>" )}, "object": "users/IeQFdqCmT9Xncfo2zNf2iugd7Yp2/Session_AmOH6ME627mVbOeIdVIT.zip"])

I couldn't figure out how to label this issue, so I've labeled it for a human to triage. Hang tight.

Hi @MalcolmnDEV, may I know if you're using simulator? Per checking the related issues, it seems to be an intermittent issue with iOS simulator.

[MalcolmnDEV]

@rizafran it was using an iPhone SE 3rd Gen iOS 18.5

[rizafran]

Just to confirm, is it a physical device or a simulator?

[MalcolmnDEV]

@rizafran this was a physical device

[MalcolmnDEV]

@rizafran Good afternoon, any update here ?

[rizafran]

Sorry for the late revert, @MalcolmnDEV. Is it possible for you to share an MCVE that reproduces the issue?
