SuperTokens TOKEN_NOT_FOUND
Understanding SuperTokens: A Brief Overview
SuperTokens is an open-source authentication solution designed to help developers implement secure and scalable authentication in their applications. It provides a range of features including session management, social login, and multi-factor authentication, making it a versatile choice for modern web applications.
Identifying the Symptom: TOKEN_NOT_FOUND
When using SuperTokens, you might encounter the TOKEN_NOT_FOUND error. This error typically manifests when an authentication request fails due to a missing token. Users might experience unexpected logouts or inability to access protected resources.
Delving into the Issue: What Does TOKEN_NOT_FOUND Mean?
The TOKEN_NOT_FOUND error indicates that the authentication token, which is crucial for verifying user identity, is absent from the request headers. This token is essential for maintaining user sessions and ensuring secure access to resources.
Common Causes of TOKEN_NOT_FOUND
- The token was not included in the request headers.
- The token format is incorrect or corrupted.
- There is a misconfiguration in the client-side code responsible for sending the token.
Resolving the Issue: Steps to Fix TOKEN_NOT_FOUND
To resolve the TOKEN_NOT_FOUND error, follow these steps:
Step 1: Verify Token Presence
Ensure that the token is being sent in the request headers. You can do this by inspecting the network requests in your browser's developer tools. Look for the Authorization header and confirm that it contains the token.
Step 2: Check Token Format
Verify that the token is correctly formatted. It should typically be a Bearer token, formatted as follows:
Authorization: Bearer <your-token-here>
Step 3: Debug Client-Side Code
Review the client-side code responsible for attaching the token to requests. Ensure that the token is being retrieved and set correctly. Here's an example of how you might set the token using JavaScript:
fetch('https://api.yourapp.com/protected-endpoint', {
method: 'GET',
headers: {
'Authorization': `Bearer ${yourToken}`
}
})
