Amphtml: For Google Amp-analytics events not captured in report if eventValue is string

[jalajc]

Observation: When eventValue is string Google Analytics doesn't show that event in reports

Even though the network tabs display that analytics _collect_ ping is sent and is successful(200 OK), this event is not visible in Google analytics report.

On the same Google Analytics config, _scroll event_ which sends integer values is immediately visible in Google Analytics dashboard. _Social Interactions_ works fine too!

PS: I have also added some _custom dimensions_ for AMP. But they are all same for other triggers such as social, pageview and event.

How do we reproduce the issue?

I discovered two conflicting documentation in this regard

1. Generic Analytics documentation-eventValue

Field Name | Protocol Parameter | Value Type | Default Value | Max Length | Supported Hit Types
------------ | -------------|------------ | -------------|------------ | -------------
eventValue | ev | integer| None | None | event

1. AMP Specific Analytics documentation-eventValue

Value | Type | Required | Description
------------ | -------------|------------ | -------------
eventValue | string | no | _A numeric value associated with the event (e.g. 42). Defaults to 0._ :exclamation:
with string sample demonstrated here

You are correct, eventValue is an integer according to GA, so the amp-analytics docs and sample code need to be updated.

Thanks @kschmidtdev for suggesting the use of eventLabel as a workaround for now.
