JSONDecodeError: Expecting value: line 1 column 1 (char 0)

I installed via conda F5 TTS. When I try to press the generate button I get this error.

That's probably because the audio text is longer than 12 seconds. There's a bug with the automatic adjustment. Just shorten it to 11 seconds and it might work.

By the way, the next error comes right after that. It says that 4 values are expected, but only 3 were provided. This means the text wasn’t extracted from the uploaded audio using “Whisper.” So you’ll also need to enter the “Reference Text.”
