BrokenPipeError: [Errno 32] Broken pipe

I created a visualization using plotly graph object (Not dash or plotly express).

Before showing the visualization in the browser, the python code has to process a lot of data and will take a little bit longer time than usual. That okay for me.

But, I am getting this broken pipe error. In StackOverflow , it says

This usually happens when you write to a socket fully closed on the other (client) side. This might be happening when a client program doesn’t wait till all the data from the server is received and simply closes a socket (using the close function).


But, the client JS code is generated and I can#t have any control over that to make it wait for a bit longer.

What can be done in this situation?

Here is the complete error trace:

Hi @mainul thanks for posting. Did you find a solution?

Unfortunately no. I moved to use matplotlib to visualize a huge amount of data.
Also this answer is helpful. Although does not solve the problem but in the similar direction.
