Verify User Token in Laravel

I have an ionic 3 application that is using laravel as backend . For auth I am using JWT and everything is working fine from registration , login and posting data within the app.

Problem starts when the user closes the mobile app and opens it again, I want the app to auto login the user using the saved token in storage.

The code below is for checking if the user has a token in storage, if there is then the token needs to be sent to laravel backend for verification.

verifyToken() {
return new Promise((resolve, reject) => {"token").then((value) => {
let headers = new Headers();
headers.append("Accept", "application/json");
headers.append("Content-Type", "application/json");
headers.append("Authorization", "Bearer " + value); + "/verifyToken", { headers: headers }).subscribe(
(res) => {
let data = res.json();
console.log("Valid token results:", data);
(error: any) => {
console.log("Token was invalid", error);

On Laravel backend I have this code for verification

 public function verifyToken()
try {

if (! $user = JWTAuth::parseToken()->authenticate()) {
return response()->json(['success' => false, 'error' => 'User not found.',$e->getStatusCode()], 404);

} catch (TymonJWTAuthExceptionsTokenExpiredException $e) {

return response()->json(['success' => false, 'error' => 'Login Token expired.',$e->getStatusCode()], 401);

} catch (TymonJWTAuthExceptionsTokenInvalidException $e) {

return response()->json(['success' => false, 'error' => 'Login Token invalid.',$e->getStatusCode()], 401);

} catch (TymonJWTAuthExceptionsJWTException $e) {

return response()->json(['success' => false, 'error' => 'Login Token not supplied.',$e->getStatusCode()], 401);


// the token is valid and we have found the user
return response()->json(['success' => true, 'message' => 'Token is valid.'], 200);


When I test this via postman and provide valid user token, I get status 200 but when I do the same on the mobile app I get an error 500

"message": "The token could not be parsed from the request",
"exception": "TymonJWTAuthExceptionsJWTException",.
