Error Categorization

By default, all unhandled promise rejections are collected as simple events and not errors. Based on the rejection message, you can categorize each rejection and tag it as an error by providing settings.plugins.unhandledRejection.errorCategorizer function in the Init Script.

The following code sample how to categorize these events as errors when their message rejection contains a string error.

const settings = germainApm.getDefaultSettings();
...
settings.plugins.unhandledRejection.errorCategorizer = (reason) => {
   return reason && reason.indexOf('error') > -1;
};
...
germainApm.start(settings);
