Bash - While loop exit code 1 - bash

Question

I have a problem with one of my bash scripts. Here is code.
#!/bin/bash

The problem with this script is that whenever I run whole run is going smoothly and perform everything that is required. However at the end it always throws error bellow.
##[error]The process '/bin/bash' failed with exit code 1
##[error]Bash failed with error: The process '/bin/bash' failed with exit code 1
I have spent quite few hours trying to debug this but i don't know what is cause of that error. Can error be caused by while loop itself?
