The error is Uncaught (in promise) in Chrome. What is the error and how to fix it?

Question

JavaScript

Hello everyone, an error has appeared on the main page of the site, I don’t understand what the trouble is and how to figure it out?
While the functionality of the site does not affect.
What port are you talking about?

Uncaught (in promise) Object {message: "The message port closed before a reponse was received."}

Answer 1

The error was due to the Wappalyzer Chrome application, turned it off and everything became normal.

Answer 2

I create websites. I opened the project, I'm working and the error "Unchecked runtime.lastError: The message port closed before a response was received." If you encounter such problems, then first check the extensions and disable them all.

Answer 3

AdGuard Anti-banner also gave the same error. Disabling the plugin no longer caused the error.

Answer 4

Also faced this problem. I solved by disabling all extensions, which stopped giving an error, then turned on each extension in turn and identified the culprit. For me it was "Web Threat Protection 360".

Answer 5

Disabled the Tab Scissors extension and everything returned to normal.
