Mutations with authorization header gives 500 error

[vorasudh]

Describe the bug
I am facing issues when a logged-in customer is trying to add to cart or checkout. I am using WPGraphQL JWT Authentication for authentication. I receive authToken, refreshToken and sessionToken. When I try to make any mutation with the authorization and woocommerce-session header, the call fails with error code 500 with this message:

<p>There has been a critical error on this website.</p><p><a href=\"https://wordpress.org/support/article/faq-troubleshooting/\">Learn more about troubleshooting WordPress.</a></p>.

Unfortunately, enabling debugging does not provide any logs in response to the mutation.

So basically a logged-in user cannot add a product to a cart (mutation: addToCart) and cannot checkout (mutation: checkout). I have looked at many previous issues (#88, #147, #297, #320), but nothing is solving my problem here. Maybe I missed some configuration here. Can someone please guide me?

Plugin Versions

• WooGraphQL Version: 0.11.2
• WPGraphQL Version: 1.11.1
• WordPress Version: 6.0.2

@vorasudh Are you testing this in a GraphQL client?

@kidunot89 Yes, i am using Apollo client in my NextJS project.

After days of debugging, it turns out that my .htaccess file already had a configuration to redirect auth header so WP can access it. And I was adding it again - SetEnvIf Authorization "(.*)" HTTP_AUTHORIZATION=$1.

Once I removed SetEnvIf Authorization "(.*)" HTTP_AUTHORIZATION=$1, it just worked nicely.
