How to search the error code of 'com.apple.coreaudio.avfaudio'?

Question

Where could I get the information of com.apple.coreaudio.avfaudio error codes, such as:

Terminating app due to uncaught exception 'com.apple.coreaudio.avfaudio', reason: 'error -50'

I always get an error while writing PCM buffer to AVAudioFile. The buffer comes from AVAudioEngine's output node.

The error:

* Terminating app due to uncaught exception 'com.apple.coreaudio.avfaudio', reason: 'error -50' * First throw call stack: (0x18eb46fe0 0x18d5a8538 0x18eb46eb4 0x1a8d051cc 0x1a8d731dc 0x1000d45e0 0x1000d4820 0x1a8d14654 0x1a8d146c0 0x1a8d8c26c 0x1a8d8c1fc 0x100ae5a10 0x100af1a84 0x100b001f8 0x100ae7a60 0x100af3128 0x100ae9634 0x100af5630 0x100af6f48 0x18dc0968c 0x18dc0959c 0x18dc06cb4) libc++abi.dylib: terminating with uncaught exception of type NSException
