After calling builder.AddAzureKeyVault() custom function route Prefix is reset to default

[bigeasy77]

I have a custom prefix set up for my function in host.json file:
{ "version": "2.0", "extensions": { "http": { "routePrefix": "" } } }

So this means there should be no prefix and my function URL should look like
https://<hostname>/myendpoint
instead of default "api" prefix
https://<hostname>/api/myendpoint

But whenever I call builder.AddAzureKeyVault(...) in my Startup the custom prefix value is not taken into account and the default 'api' prefix is added

Thanks!
