Need urgent help with google maps

Hi,
Is the bubble documentation on google maps API integration up to date?
I have followed all the instructions, got my Maps API key, enabled billing still I am getting this error.
Kindly point me in the right direction, googles documentation is something which I just can’t understand, it’s all loop, click here and reach page 2, click on a link on page 2 and you reach back to page one.

At best I could reach this error by clicking on menu> more tools> developer options> esc. on chrome browser.

Solved by google, the issue was with google policy that changed in Nov 2018.
Here is the link to it’s documentation if required by some member from India.
