Events not being sent, only until after the connection was closed

[willemmulder]

Describe the bug I have two scenarios where the Speechmatics SDK is not returning an Event that I expect. Only after I close the connection, the event is returned. Not sure if it's the API or the SDK that is the culprit.

Two examples:

• For a short audio file (few kb. two sentences), the first sentence is successfully returned, but the second sentence is never returned. Only when I close the connection or send "EndOfStream" explicitly, the sentence suddenly arrives.
• For an invalid audio file (11 bytes, with UTF content "Not found.\n") I do not get anything from the SDK. No error, no transcription, nothing. Only when I close the connection, I get

Speechmatics session error { message: 'Error', type: 'invalid_audio_type', reason: 'Invalid audio type: Could not determine type of stream.' }

To Reproduce

• Create file with "Not found.\n".
• Send it to the SDK
• See that nothing happens
• Close the connection
• See that an Event arrives

Expected behavior I expect for the two scenarios

1. Short files should be fully transcribed, It feels as if Speechmatics keeps on waiting for more audio. However, setting max_delay does not help either.
2. Invalid files should immediately be rejected with an Error.

Desktop (please complete the following information):

• OS: WIndows and Linux
• Version 3.x and 4.x

@willemmulder thanks for this - I was able to reproduce both issues, we'll take a look.
