I am trying to make a block which copies (samples_per_symbol * no. of symbols ) samples from the input 0 stream whenever it receives a trigger (i.e. a 1) in input 1 stream.
My block is giving expected output when it runs but when it does not work in gnuradio companion it gives this error.
Traceback (most recent call last):

I am attaching both the flowgraph that I use for testing and the code I a have written for creating OOT module.
The code is almost similar to the code of header_payload_demux block.
Please look into this as soon as possible.
