thanks for bringing python option to Camunda External Tasks

I have been trying to use your library. Used your sample code just as it is, and included my business logic in it, but always receive an error saying youNevertheless I installed it with pip as the instructions say, and checked the directories are there. Also sure my python is 3.7 (3.7.9 actually).

Do you have an idea what am I could be missing ?

Thanks in advance

@Luis check if PIP is already installed

pip help


pip --version

If PIP responds, then PIP is installed. Otherwise, there will be an error saying the program could not be found.

PIP is automatically installed with Python 2.7.9+ and Python 3.4+.

Follow this tutorial for PIP installation and verification.

What is the error you are getting? please provide detailed error and stack trace.
