Issue about timeout in Speech to text Long model v2

[Pathorn]

Hi Google Team, I have an issue with the timeout in the long-run requests. I use the input file as 1hr 30 mins, 3 hours 45 mins, and 1 hour respectively. This progress should work because batch recognition for the long model in speech v2 supports up to 480 mins/8 hours of audio. Even I adjust the result(timeout=None) or result(timeout=9999999999999). This still does not work and an error shows that timeout for 900 s.
