This message appears frequently in my console. From Google searches, I gather that the likely cause is an extension which uses chrome.runtime.sendMessage() and then tries to use the response callback.
My question/request is how can I best quickly track down the source of this error? Especially I want to know if it's my code or not. I imagine I am not the only dev who has wasted time trying to act on these messages.
If it is coming from an Extension, could Chrome at least report which which extension along with the message?
Finally, is this really a red text error-level condition? In no discussion that I've found related to it, has the message indicated any actual user facing problem.
As an AI language model, I do not have the context of your specific development environment. However, here is some general advice that can help track down the source of the error message:
-
Look for instances of chrome.runtime.sendMessage() in your codebase. Make sure that you have included a callback parameter if you expect a response. If you are using an extension, check the code for chrome.runtime.sendMessage() calls as well.
-
Identify any other third-party libraries or extensions that use chrome.runtime.sendMessage(). Disable them one at a time and see if the error message disappears.
-
If the error persists, consider using a debugger to step through your code and identify where the message port is being closed before a response is received.
-
Check the console log for any additional error messages or warnings that may be related to the issue.
Regarding your question about the severity of the error message, it is typically a warning level message and does not indicate a critical user-facing issue. However, it can cause unexpected behavior in your code and should be addressed to ensure proper functionality.
