To fix the problem, ensure that the code has access to an actual sign function at the point where it is being called. In JavaScript projects, JWT signing is typically provided by the well-known external library jsonwebtoken. The best fix is to import the jsonwebtoken library, assign it to a suitable variable (such as jwt), and use its sign method.

• Change the local jwt object’s name slightly (e.g. to jwtHelpers), OR explicitly import jsonwebtoken as jwt, so the existing call (jwt.sign(...)) works.
• Ensure that any subsequent code that relies on the local custom jwt object refers to the renamed jwtHelpers.
• Insert the required import statement for jsonwebtoken.
• Modify all references in the code where the local helper functions (decode, isExpired) are used, updating them to refer to the new identifier if the object is renamed from jwt to jwtHelpers.

Files/regions to change: Only frontend/src/main.js, specifically lines:

• Line 21: Ensure jwt.sign is defined.
• Line 34: Rename/replace the local jwt object to avoid collision.
• References to jwt.decode, jwt.isExpired (lines 41, 174, 189): Update to point to new helper object name.

Methods/imports to add:

• Add import * as jwt from 'jsonwebtoken' at the top.
• No need to define a custom sign function if using jsonwebtoken.
• Rename the local helper object to jwtHelpers, update all uses.

To resolve the unused variable error for oldToken, simply delete the declaration from line 21–23. This removes unnecessary code and avoids the pointless creation of a JWT token that is never used.
No other dependent code references this variable, so this fix does not affect any existing functionality.

• In frontend/src/main.js, remove lines 21–23 which declare and assign oldToken.
• No changes to imports or other code blocks are needed.

To fix the problem, we need to ensure that any references to jwt occur only after its declaration. More specifically:

• On line 21, jwt.sign(...) is clearly intended to call the sign method, which does not exist on the locally defined jwt object (which only has decode and isExpired), but is a method of the popular jsonwebtoken library's jwt object.
• The best fix is to add an import or require statement for the jsonwebtoken library at the top of the file, assign it to a new variable (e.g., jsonwebtoken), and use this for sign. This avoids conflict with the custom local jwt object and ensures the correct method is called.
• Change line 21 to use jsonwebtoken.sign(...) instead of jwt.sign(...).
• Optionally, provide a comment to clarify the distinction between jsonwebtoken (the external library) and the custom jwt object.

All code changes occur in frontend/src/main.js:

• Add import jsonwebtoken from 'jsonwebtoken' at the top, after existing imports.
• Change line 21 from jwt.sign... to jsonwebtoken.sign....
• No other changes are required.
