While runing python conductor I am getting following error. EOFError: Ran out of input:

The detailed stacktrace is given below:

I got the same error. I'm using a windows machine, so I tried using a linux docker container instead, and it worked.

Hi @arunksoman

Thanks for reporting this issue! This appears to be the same pickling error that was discussed in another thread. The solution has been provided there - please check out this comment for a working workaround.

Let me know if you try the solution and still encounter problems - I'd be happy to help troubleshoot further!
