Recently, while working with the Field Service app, we ran into a strange issue. Every time we tried to create a new Account with address information, the system threw an error:

At first, this message didn’t tell us much as this is generic message. A “403 Forbidden” usually means something is blocked or not authorized, but I was using Sys Admin role so there this was strange to me. I started troubleshooting further and found that we were only getting error when populating address details.
While checking error log file I found that one of the Field Service plugin for geocoding was failing. We opened Microsoft support case and while troubleshooting with team we found that this error was coming from the Bing Maps integration used in the Field Service app. Our Bing Maps Key was either expired or not valid, which caused the system to block the request when creating an Account (because of geocode plugin). We removed this key and tested account creation again – and it worked without any errors. It was geocoding fine without this key as well

Summary
If you see a “403 Forbidden” error when creating records in Field Service, don’t forget to check the Bing Maps Key configuration. A missing or invalid key can silently cause issues that look unrelated at first.
Hope it will help someone!!
