Azure Static Web Apps: Custom Authentication with Azure Functions scenarios with 403 Forbidden
I'm using Azure Static Web Apps with a custom authentication setup that involves Azure Functions. The goal is to protect certain routes in my app using an Azure Function to verify JWT tokens. When I try to access a protected route, I receive a `403 Forbidden` behavior, even though I'm passing what I believe to be a valid token. Here's the structure of my Azure Functions setup: - Azure Function URL: `https://<yourapp>.azurewebsites.net/api/validateToken` - JavaScript code for the function: ```javascript module.exports = async function (context, req) { const token = req.headers['authorization']?.split(' ')[1]; if (!token) { return context.res = { status: 401, body: 'Unauthorized' }; } // Token validation logic goes here const isValid = validateYourTokenFunction(token); if (!isValid) { return context.res = { status: 403, body: 'Forbidden' }; } context.res = { status: 200, body: 'Valid Token' }; }; ``` I've tried debugging and logging the token in the Azure Function, and it seems to be received correctly. I even tested the token through Postman, and the validation works fine. However, when I integrate it with my Static Web App, the response is inconsistent. In the `staticwebapp.config.json`, I have the following route configuration: ```json { "routes": [ { "route": "/api/protected/*", "allowedRoles": ["authenticated"] } ] } ``` I’ve double-checked the role settings in the Static Web App environment and confirmed that the user is authenticated. Additionally, I’ve ensured CORS settings allow requests from my frontend. Could there be any misconfigurations regarding the role validation in the routing, or is there an scenario with how the Azure Functions handle the JWT token in the context of Static Web Apps? Any insights or suggestions would be greatly appreciated!
