Quick Fix: Examine the response headers in your browser’s console to see which CSPs are set, modify the script-src directive to allow js.stripe.com if you have control over the CSP, remove the CSP by proxying requests if you don’t.
The Problem:
I am unable to load a script within my Chrome web extension due to a Content Security Policy (CSP) directive violation. Specifically, the error message mentions that the script is trying to load from a URL (‘https://js.stripe.com/v3/buy-button.js’) that is not allowed by the CSP directive. The CSP directive is set to ‘script-src ‘self’ ‘wasm-unsafe-eval’ ‘inline-speculation-rules’ http://localhost:* http://127.0.0.1:*’ which means that scripts can only be loaded from the same origin, or from specific allowed domains. How can I resolve this issue and load the necessary script?
The Solutions:
Solution 1: Checking Response Headers
The error message indicates that there is a mismatch between the Content Security Policy (CSP) directives in the meta tag of your index.html and the one set in the response headers. To resolve this issue, follow these steps:
Check Response Headers: Use a network analysis tool (e.g., Chrome DevTools) to inspect the response headers for your index.html. Look for the Content-Security-Policy header.
Compare Directives: Compare the script-src directive in the response headers with the one defined in the meta tag. Ensure they match and allow the loading of js.stripe.com.
Modify CSP: If the response headers have a more restrictive CSP, you may need to modify it. If you control the response headers (e.g., by modifying the web server configuration), change the script-src directive to allow js.stripe.com.
Proxy Requests: If you do not control the response headers (e.g., because they are set by a third-party website), you may need to proxy the requests to js.stripe.com through your own server. This allows you to set the appropriate CSP.
Solution 2: Modify Content Security Policy
Within your manifest.json file, adjust the “web_accessible_resources” property to include the specific JavaScript file:
“`json
“web_accessible_resources”: [
“https://js.stripe.com/v3/buy-button.js”
],
“`
Moreover, remove the ‘unsafe-inline’ and ‘unsafe-eval’ values from the meta tag in your index.html file:
How can I fix this CSP issue by using the "web_accessible_resources" property?
—
Update the manifest.json file by adding the blocked script to the "web_accessible_resources" array.
How can I fix this CSP issue by modifying the meta tag?
—
Remove the ‘unsafe-inline’ and ‘unsafe-eval’ values from the meta tag’s Content-Security-Policy directive.
