this is already done by createAwsService(), which is called on line 42 above.

[justinmk3]

is a caller to createFeatureDevProxyClient perhaps passing customUserAgent and overriding this?

[chengoramazon]

I can not see where customUserAgent predefined in createAwsService. Can you point me to the right place?

I have verified there are not callers override the customUserAgent.

	if (userAgent && !opt.customUserAgent) {
	opt.customUserAgent = getUserAgent({ includePlatform: true, includeClientId: true })
	}
