Technical logging if the application fails

Hi,

I'm doing some testing for my organisation to see how we mighr fix any technical issues in the PowerBI service, and if there is any technical logging within the service that would help me to find the root cauase of any issues.

For example. Does the service provide any of the following information, and where I mighr I find this in the web application:

1. Are there any error codes/,essages that would appear if an issue occured

2 Would these have any severity codes against them? e.g. High, Medium low

3. Are these error codes easy to undersyand and fix

Sorry for the basic questions, I am doign a system implementation and need to evidence such information.

Thanks!
