Adguard and uBlock Origin can block identify call

[domano]

Describe the bug If i use the client-sdk & the identify-call then certain adblockers will prevent me from calling identify.

This results in new users not showing up, which means we can't target them. Default environment settings for flags work. Disabling the adblockers solves the issue.

To reproduce Try to identify a new user with Adguard or uBlock Origin

Expected behavior I would have expected that identification works. Logs If applicable, add any log output related to your problem.

SDK version The version of this SDK that you are using.

OS/platform Had this happen in Safari and Chrome with different versions, using Adguard and/or uBlock Origin.

Thanks for the great product, apart from this it has been a really great experience!

Hi @domano, this is called out in our documentation here: https://docs.launchdarkly.com/sdk/client-side/javascript#browser-support. A couple of important clarifications here:

• The identify call is working; the ad-block extensions only block the resulting event data from coming back to LaunchDarkly, and does not affect flag evaluations or the changing user context from an identify call.
• The SDK uses the attributes supplied in your code for flag evaluation, and does not look at the Users dashboard for evaluating flags at all.

I'll go ahead and close this issue, but if you have further questions on this, please don't hesitate to open a support ticket with us at support@launchdarkly.com and we'll be happy to help you further there.
