I'm currently creating a quite easy chrome extension which open a new window with a simple URL, and inject JS in this new window.
But I have this issue : "Uncaught (in promise) Error: Cannot access contents of url "". Extension manifest must request permission to access this host."
I'm pretty sure of my code and my manifest, and I really can't find any solution.
My code:
chrome.windows.create({url: "http://www.google.fr", type: "popup", width: 1240, height: 768, focused: true}, tab => {
chrome.scripting.executeScript({
target: { tabId: tab.tabs[0].id },
function: test,
});
})
function test(){
alert('it's working');
}
My manifest:
{
"name": "COSMO Heatmap",
"description": "Description à faire",
"version": "1.0",
"manifest_version": 3,
"background": {
"service_worker": "background.js"
},
"content_security_policy": {
"extension_pages": "script-src 'self'; script-src-elem 'self' 'unsafe-inline' https://ajax.googleapis.com; object-src 'self'"
},
"permissions": ["storage", "activeTab", "scripting", "unlimitedStorage", "tabs","webRequest", "<all_urls>"],
"host_permissions": ["<all_urls>"],
"optional_permissions": ["<all_urls>"],
"action": {
"default_popup": "popup.html",
"default_icon": {
"16": "/images/CosmoLogo.png"
}
},
"icons": {
"16": "/images/CosmoLogo.png",
"32": "/images/CosmoLogo.png",
"48": "/images/CosmoLogo.png",
"128": "/images/CosmoLogo.png"
}
}
