OpenId Connect Redirect Callback Error When User Cancels

I am currently working on a basic Azure SWA application that is using Azure B2C as its Identity Provider. We have noticed when a user hits "Cancel" in the account creation process it redirects back to the application as expected with an error appended to the callback function URL as a query as such.

`
/.auth/login/b2c/callback?error=access_denied&error_description=AADB2C90091%3a+The+user+has+cancelled+entering+self-asserted+information.%0d%0aCorrelation+ID%3a+165c89e1-8b2a-40e3-9fb8-95560ea6de2f%0d%0aTimestamp%3a+2021-12-07+17%3a48%3a08Z%0d%0a&state=%2f.auth%2fcomplete`

Successful logins and their redirects work as expected. However, this callback erroring is returning a 401 back to the user and displays JSON to the user as if it's an HTTP request (see screenshot below for the white page). We have tried to add a redirect in the configuration to handle response codes of 401 but it seems as if the configuration is being ignored when the 401 is triggered by the callback erroring out. Also adding for more context, this is an out-of-the-box SUSI user flow. Below is my static config file as well, if anyone has any insights or needs further information I'll happily get more detail over.

"route": "/",
"allowedRoles": [ "authenticated" ]
}
],
"responseOverrides": {
"401": {
"redirect": "/.auth/login/b2c",
"statusCode": 302
}
},

}
}
}
}
}
}
```
