Dialogflow CX - Location settings have to be initialized - FAILED_PRECONDITION - dialogflow-cx

Question

I am automating Dialogflow CX using Python client libraries. That includes agent/intent/entity etc. creation/updation/deletion.
But for the first time run, I am encountering the below error from python.
If I login to console and set the location from there and rerun the code, it is working fine. I am able to create agent.
Followed this URL of GCP -
https://cloud.google.com/dialogflow/cx/docs/concept/region
I am looking for code to automate the region & location setting before running the python code. Kindly provide me with the code.
Below is the code I am using to create agent.
Error -

Answer 1

Currently, Dialogflow does not support configuring the location settings through the API, thus you can not initialise location settings through it. You can only set the location through the Console.
As an alternative, since the location setting has to be initialised only once for each region per project you could set the location and automate the agent creation process, some useful links: 1 and 2.
On the other hand, if you would find this feature useful, you can file a Feature Request, here. It will be evaluated by the Google's product team.

Many thanks Alexandre Moraes. I have raised a feature request for the same.
