Azure Function exception logging to application insight

Question

Logging to application insight when there is an exception in an Azure function project but only exception message is logged, I want to add custom property

Answer 1

catch(InvalidStatusCodeException status_ex)
{
     log.LogError(status_ex, "Invalid Status code for request: '{ApiUrl}', received code: {ReceivedStatusCode}", status_ex.ApiUrl, status_ex.ReceivedStatusCode);
 }

The above log will add ApiUrl and ReceivedStatusCode as custom properties in application insights log.
