Missing whitelisted parameter in "event" method config

[maxijb]

p is missing among the whitelisted params for the .event method.

This results in warnings like this:
Warning! Unsupported tracking parameter p

In config.js I only see these parameters allowed:

  // Event Tracking
   "ec", "ea", "el", "ev",

There is no documented parameter p for the Measurement Protocol. Would you elaborate what you're referring to?

[jarrodek]

What he refers to is that the library sets p parameter in the event function:

params.p = params.p || params.dp || this._context.p || this._context.dp;

Which leads to a warning in debug mode:

universal-analytics Warning! Unsupported tracking parameter p (/xxx) +3ms

To reproduce:

let chain = this.ga.ua.pageview('/xxx');
chain = chain.event('My category', 'My action');
chain.send();

Run this in debug mode to see warnings.

I believe the intention was to use dp parameter (document path) which can be combined with events.

Ran into this as well, I used dp as follow:

const eventParams = {
        ec: category,
        ea: action,
        el: label,
        ev: value,
        dp: path,
        // userAgentOverride: userAgent,
        av: `${process.env.GIT_COMMIT_VERSION || ''}`
      };

universal-analytics Warning! Unsupported tracking parameter p (/idrac/chatbot/_student-solutions)

But the dp is there at

universal-analytics/lib/config.js
