You want to use Power Virtual Agent with Dynamics 365 Customer Service, and you are trying to install the extensions to activate variables and actions.
You are following precisely the path described in the documentation, but you get an error message saying the solution is not compatible with your environment. In my case, all language settings are on en-US, but my tenant has a location in Germany.
If you're facing an error and need help resolving it, you've come to the right place. While the solution presented here may be specific to my machine, it should help you pinpoint the root cause of the issue and find a fix that works for you. Let's get started!
Here comes a dirty workaround to get it done in between.
Open the developer tools in your browser (Edge: CTRL+SHIFT+I) and open the Network Tab. While clicking on "install", you will see an error "400"
exchange the countryCode to "US"
"countryCode" : "US"
copy it back to developer tools and
Click on the send button.
You will then recognize a result code "200" in the status line.
If you close the installation popup and go straight to the environment you want to install the extensions to, you will see that this "fix" was successful.
Do not give up when something unexpected happens. Find the root cause with the tools you have and give a first thought a try.
