I have an azure bot, and I am adding a private endpoint. I am working through this document: Private Endpoint & Direct Line App Service Extension Configuration with Bot Services and App Service
I completed the 'Enable bot Direct Line App Service extension' section, but when I make the call to confirm the direct line extension and bot are configured I get a value of false from initialized.
The call to https://<your_app_service>.azurewebsites.net/.bot returns: {"V":"1.2.0.0.e84fbf1863c30abdf7b40dc11a91bc86044d49a2","K":true,"IB":true,"OB":true,"Initialized":false}
According to the document, a value of false means the Direct Line App Service extension is unable to validate the App Service extension key. I have triple checked that the key is valid, and I have tried using the alternate key.
How can I find more information about why it can't validate the key?
How can I troubleshoot this?
