Issue

Describe your issue here
In my IOS project, when making a call to firebase functions in Release mode, I am encountering -[NSNull length]: unrecognized selector error.

Interestingly, the call works fine when running in Debug mode on IOS. On Android, everything works correctly in both Debug and Release modes. I'll also note that authorization calls and calls to firestore work fine in both release and debug mode for both platforms.

In the "JavaScript" section of the provided bug reporting template, I included the simple function call that is triggering the error.

The crash logs do not provide a lot of detail and I have spent numerous hours trying to figure out what is happening, with no luck.

The only error I receive:
"libc++abi: terminating due to uncaught exception of type facebook::jsi::JSError: Exception in HostFunction: -[NSNull length]: unrecognized selector sent to instance 0x1e4877140

Error: Exception in HostFunction: -[NSNull length]: unrecognized selector sent to instance 0x1e4877140"

Additionally, Xcode indicates the (red) X next to Thread 2 Queue : com.meta.react.turbomodulemanager.queue (serial)

The crash logs do not point to any particular line, but I did see that within the functions library/pod, the Functions file on line 486 the does point to an NSNull() variable:
let data = data ?? NSNull()

Just a wild guess at this point, no idea. Please advise, thanks.

Hey 👋 ! I've got good news and bad news - good news first. Lucky winner, this crash doesn't have a lot of information but I reproduce it immediately in our test harness! (this is a rare thing, and usually the hardest part of the triage effort)

bad news is, yes, there is some sort of unexpected crash in iOS release mode - obviously we test debug mode in our day to day so we never saw this.

I'm going to open a PR tagged to close this bug but please understand all it is doing is setting up our e2e test harness to allow for release builds + runs, it did not before. No fix yet unfortunately
