Hi @elder hull. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
#CSP- ISSUE
blazing gladeBOT
The issue you're facing is related to the Content Security Policy (CSP) of your Next.js application. CSP is a security feature that helps to prevent various security threats such as cross-site scripting (XSS), clickjacking, and other code injection attacks. It allows developers to specify which origins are permissible for content sources, scripts, stylesheets, images, fonts, objects, media (audio, video), iframes, and more [source (https://nextjs.org/docs/app/building-your-application/configuring/content-security-policy)].
In your case, the CSP is blocking an inline script from executing because it violates the directive: script-src 'self' <https://accounts.google.com.> This means that your CSP only allows scripts to be loaded from your own site ('self') and <https://accounts.google.com.>
If you're trying to load scripts from another source (like the OAuth provider), you'll need to add that source to your CSP. You can do this in your next.config.js file. Here's an example of how to set the CSP header:
const cspHeader = `
default-src 'self';
script-src 'self' 'unsafe-eval' 'unsafe-inline' <https://accounts.google.com;>
style-src 'self' 'unsafe-inline';
img-src 'self' blob: data:;
font-src 'self';
object-src 'none';
base-uri 'self';
form-action 'self';
frame-ancestors 'none';
upgrade-insecure-requests;
`
module.exports = {
async headers() {
return [
{
source: '/(.*)',
headers: [
{
key: 'Content-Security-Policy',
value: cspHeader.replace(/\n/g, ''),
},
],
},
]
},
}
Please replace <https://accounts.google.com> with the URL of the OAuth provider you're using if it's different. Also, be aware that using 'unsafe-inline' can potentially open up your site to XSS attacks, so use it cautiously.
If you're using nonces, you can use Next.js middleware to generate a fresh nonce for each page view and add it to your CSP [source (https://nextjs.org/docs/app/building-your-application/configuring/content-security-policy#adding-a-nonce-with-middleware)].

@blazing glade my config is next.config.mjs : /** @type {import('next').NextConfig} */
const nextConfig = {};
export default nextConfig;

Let me check the knowledge base for you. One moment! :books:
If you're using a next.config.mjs file, you can set the Content Security Policy (CSP) by adding a headers function to your Next.js configuration. Here's an example of how to do it:
/** @type {import('next').NextConfig} */
const nextConfig = {
async headers() {
return [
{
source: '/(.*)',
headers: [
{
key: 'Content-Security-Policy',
value: `
default-src 'self';
script-src 'self' 'unsafe-eval' 'unsafe-inline' <https://accounts.google.com;>
style-src 'self' 'unsafe-inline';
img-src 'self' blob: data:;
font-src 'self';
object-src 'none';
base-uri 'self';
form-action 'self';
frame-ancestors 'none';
upgrade-insecure-requests;
`.replace(/\n/g, ''),
},
],
},
]
},
}
export default nextConfig
This configuration will add the CSP header to all responses from your Next.js application. Please replace <https://accounts.google.com> with the URL of the OAuth provider you're using if it's different. Also, be aware that using 'unsafe-inline' can potentially open up your site to XSS attacks, so use it cautiously.
If you're using nonces, you can use Next.js middleware to generate a fresh nonce for each page view and add it to your CSP [source (https://nextjs.org/docs/app/building-your-application/configuring/content-security-policy#adding-a-nonce-with-middleware)].

@blazing glade how do i fix Content-Security-Policy: The page’s settings blocked an inline script (script-src-elem) from being executed because it violates the following directive: “script-src 'nonce-aUlrUTh1IWcnLmrltLf4ow' 'unsafe-inline' 'unsafe-eval'” in Next.js 14.2.15

Let me check the knowledge base for you. One moment! :books:
The error message you're seeing indicates that an inline script on your page is being blocked because it violates your Content Security Policy (CSP). The CSP directive script-src 'nonce-aUlrUTh1IWcnLmrltLf4ow' 'unsafe-inline' 'unsafe-eval' allows scripts that have a nonce attribute with the value 'aUlrUTh1IWcnLmrltLf4ow', as well as scripts that use 'unsafe-inline' or 'unsafe-eval'.
If you're seeing this error, it means that there's an inline script on your page that doesn't have the correct nonce value. To fix this, you'll need to ensure that all inline scripts on your page have a nonce attribute with the correct value.
In Next.js, you can use the next/script component to add inline scripts with a nonce. Here's an example:
import Script from 'next/script'
function MyComponent() {
return (
<div>
<Script nonce="aUlrUTh1IWcnLmrltLf4ow">
{`console.log('Hello, world!')`}
</Script>
</div>
)
}
export default MyComponent
In this example, the inline script console.log('Hello, world!') has a nonce attribute with the value 'aUlrUTh1IWcnLmrltLf4ow', which matches the nonce value in your CSP directive.
If you're generating nonces dynamically (which is a good practice for security reasons), you'll need to ensure that the nonce value you're using in your next/script components matches the nonce value in your CSP directive. You can do this by storing the nonce value in a variable or a context and passing it to your next/script components.
Please note that using 'unsafe-inline' and 'unsafe-eval' in your CSP can potentially open up your site to cross-site scripting (XSS) attacks, so use them cautiously [source (https://nextjs.org/docs/app/building-your-application/configuring/content-security-policy)].

Let me check the knowledge base for you. One moment! :books:
The error message you're seeing indicates that an inline script on your page is being blocked because it violates your Content Security Policy (CSP). The CSP directive script-src 'unsafe-eval' allows scripts that use 'unsafe-eval'.
If you're seeing this error, it means that there's an inline script on your page that doesn't use 'unsafe-eval'. To fix this, you'll need to modify your CSP to allow the sources from which your scripts are being loaded.
In your Next.js configuration file (next.config.js or next.config.mjs), you can set the CSP header to include 'self' (which allows scripts loaded from your own site) and any other sources you need. Here's an example:
/** @type {import('next').NextConfig} */
const nextConfig = {
async headers() {
return [
{
source: '/(.*)',
headers: [
{
key: 'Content-Security-Policy',
value: `
default-src 'self';
script-src 'self' 'unsafe-eval';
style-src 'self' 'unsafe-inline';
img-src 'self' blob: data:;
font-src 'self';
object-src 'none';
base-uri 'self';
form-action 'self';
frame-ancestors 'none';
upgrade-insecure-requests;
`.replace(/\n/g, ''),
},
],
},
]
},
}
export default nextConfig
Please replace 'self' with the URL of the sources you're using if they're different. Also, be aware that using 'unsafe-eval' can potentially open up your site to cross-site scripting (XSS) attacks, so use it cautiously.
