For context, I am building a dashboard summarizing events, traces, and exceptions across multiple environments on Azure.
I am using the opencensus github project at
https://github.com/census-instrumentation/opencensus-python/tree/master/contrib/opencensus-ext-azure
I am able to fetch and retrieve the customEvents logs, but only through the Azure portal.

The API Explorer returns no data.

For reference
App Insights logging in JS and TS trackEvent has no issue.
I cannot find any documentation on why this is happening nor how to query the logs outside of the Azure portal.
