NestJS context is wrong whenever I try to pass through role guard

Question

I have created an API that successfully logs a user in, and returns a JWT access token with an ID, email and name. I then try to use this access token to perform a 'getAllUsers' request which requires admin privileges. I know that the user is logging in, because I decode the token returned from the login and it provides the correct details. However, when I console log the user from the context in the role guard, it is showing a different user in the database. I think I need to be setting the context somewhere but I'm not sure how. Please help! First time making a project in NestJS :)

User Controller

@HttpCode(200)
@UseGuards(LocalAuthGuard)
@Post('login')
@ApiOperation({summary: 'Log in with an email and password'})
login(@Body() user: any) {
    return this.authService.login(user);
}

Auth Service

async login(userDetails: any) {
    const email = userDetails.email;
    const user = await this.userService.getUserByEmail({where: {email}});
    const payload = { email: user.email, role: user.role, id: user.id };
    return {
        access_token: this.jwtService.sign(payload),
    }
}

Role Guard

const RoleGuard = (role: Role): Type<CanActivate> => {
    class RoleGuardMixin extends JwtAuthGuard {
      async canActivate(context: ExecutionContext) {
        await super.canActivate(context);
        const request = context.switchToHttp().getRequest<RequestWithUser>();
        const user = request.user;
        console.log(user);
        return user?.role.includes(role);
      }
    }
    return mixin(RoleGuardMixin);
  }
