In my extension I'm trying to attach debugger for given tabId, Here is my code
if(!attachedTabIds.includes(tabId)) {
chrome.debugger.attach({ tabId: tabId }, version, function(){
...
})
}
So from time to time I'm getting this error
I tried to wrap it with try/catch block but it didn't work.
try {
chrome.debugger.attach({ tabId: tabId }, version, function(){
...
})
} catch(e){
console.log('e', e)
}
SO how can I handle this error ?
You handle the error by checking the value of chrome.runtime.lastError in the callback function that you passed to chrome.debugger.attach()
if (!attachedTabIds.includes(tabId)) {
chrome.debugger.attach(
{tabId: tabId},
version,
function() {
if (chrome.runtime.lastError) {
console.log("Error");
console.log(chrome.runtime.lastError);
}
else {
console.log("Success");
}
}
);
}
https://developer.chrome.com/docs/extensions/reference/runtime/#property-lastError
lastError
This will be defined during an API method callback if there was an error
