Hello,

I had this issue on my hosting server so I upgraded to 4.1.1 but now I have this error:

Error while decoding from JSON

Stacktrace
/home/clients/9ec8ad5583918ce55944b1cc6bdd9057/web/releases/95/vendor/lcobucci/jwt/src/Encoding/JoseEncoder.php:41 /home/clients/9ec8ad5583918ce55944b1cc6bdd9057/web/releases/95/vendor/lcobucci/jwt/src/Token/Parser.php:67 /home/clients/9ec8ad5583918ce55944b1cc6bdd9057/web/releases/95/vendor/lcobucci/jwt/src/Token/Parser.php:30

I use it with Laravel 8.28.1 & Telescope 10.1.0

PHP 7.4.15

Thanks !

That usually happens when your input string is not JSON:

jwt/src/Encoding/JoseEncoder.php

Lines 25 to 43 in f7c9bb1

/** @inheritdoc */
public function jsonEncode($data): string
{
try {
return json_encode($data, JSON_UNESCAPED_SLASHES | JSON_UNESCAPED_UNICODE | JSON_THROW_ON_ERROR);
} catch (JsonException $exception) {
throw CannotEncodeContent::jsonIssues($exception);
}
}
/** @inheritdoc */
public function jsonDecode(string $json)
{
try {
return json_decode($json, true, self::JSON_DEFAULT_DEPTH, JSON_THROW_ON_ERROR);
} catch (JsonException $exception) {
throw CannotDecodeContent::jsonIssues($exception);
}
}

The library is correctly throwing an exception here.

Ok but my JSON didn't change 🤨
I switched to 3.4.5 and I works now

@cyrilbosson can the string you are trying to encode (with 3.x) be posted here (as in no NDA'd secrets)? Can you perhaps provide a full JWT token string? Can you try looking at it on https://jwt.io/ ?

Also, I wonder if some of the fields you are trying to encode contain non-utf8 characters (which leads to null output for fields, but would throw when using JSON_THROW_ON_ERROR)

@cyrilbosson I cannot reproduce your issue using the latest version of the lib and the token in the access_token property you sent:

<?php
declare(strict_types=1);

use Lcobucci\JWT\Encoding\JoseEncoder;
use Lcobucci\JWT\Token\Parser;
use Lcobucci\JWT\UnencryptedToken;

require 'vendor/autoload.php';

$token = (new Parser(new JoseEncoder()))->parse(
    'eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1NiJ9.eyJhdWQiOiIxIiwianRpIjoiNDIyZDUyNTRkNWZjZTM5OWFhNThhYWU5ZGJmZDBmNTUwM2JiOWQ4OTgwYTcwNzJjZDk5NTcyMTg1NzcwODYyZjZhNDUwNTQ2ZTIyNjk4ZjUiLCJpYXQiOjE2MTM1ODE2OTQsIm5iZiI6MTYxMzU4MTY5NCwiZXhwIjoxNjQ1MTE3Njk0LCJzdWIiOiI1OSIsInNjb3BlcyI6W119.nNA0Uz9uLptDAJ57rmnYnoP80bp2eGlqPbv3jkANGgXLPm1W8GxibEyKMivzgg_7U5I4D5_IB19OR9ESTg_tNUztBydFSNsYnmsxuQxiH3cKt-1-JzeVyYORUhk1cPPlKp7g_s3hZxSWjCwtmeYdfitpvA7MvVhZfLCZG1UC5ukrrCrsM84_itdb5QFNGL6RwXPwBDGzdVHLX9MaBgB4oL6K_QtfauW6ki2TracqzTYtzCbTGSnVVSR5yFBnnzXd_uyx0schZneLSEQRUOlfI1P4LRhvn_dfzMfHQ8GMZEpuoHrPPnioQym8EV5lXmWzfC2TKi0nV1W89e-_W8apWchFtIDeg6wpRCNiGgMUomz4bPpCxUH13XSJIzELFSWCehH4dZcvnAW-K9788H3UExgCc5hQlcKdIONlWLUlAvWLNR58huaFA1TAcLfiuv3Xjjv4G9ihmdo47dtDlyWpsXlCZE56HycKZwwCC0_F49ws9C4ZsrbCYk1Cq5-gY_55ruqfTURk0pNVwFg9bxiHQrHcxDChvnotmWi9NYmBBYrETYGP4DYrOH4_k1CHJwn3GRpW9ma8XTL75M3Ejl5DWduZnS1Yk_d59g-d5EmS6862_giyWMATuStufnpibgLT8jaViuQ2TfcEVArijS07KKk7IJADavXgPh6ZAFECDC8'
);

var_dump($token instanceof UnencryptedToken); // bool(true)

Can you provide more information or check if your application is sending the JWT properly to the parser?

I am facing similar error. Its working fine in other dedicated server but not in Shared Hosting.
Code and even project is same in both server.

My Token:

My Code to parse the token.

can you help me ?

I can see this in your trace:
json_decode('ZXlKMGVYQWlPaUp
You aren't decoding JSON there?
…

no, its working in other server(nginx). I am passing raw string to parse which is stated in Documentation.

I can clearly see this:

#1 /home/smartmpsco/public_html/cust/rms/api/vendor/lcobucci/jwt/src/Token/Parser.php(67): Lcobucci\JWT\Encoding\JoseEncoder->jsonDecode('ZXlKMGVYQWlPaUp...')

That means that gibberish is passed to JSON decoding logic :-)

The exception is just the symptom.

Locking this thread: please do write an integration test about your use-case, before reporting a new issue with a reproducible scenario.

Is it possible that a bug in libsodium is the thing to blame here? That's the only explanation I have for it to fail on specific servers only. @Slamdunk have you experienced something like this?

@lcobucci
Copy link
Owner

@amrishkakadiya can you run the following code on both the new and old servers:

<?php

$headers = 'eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9';

var_dump(
    base64_decode(strtr($headers, '-_', '+/'), true), 
    sodium_base642bin($headers, 7, '') 
);

Dedicated server response
string(27) "{"typ":"JWT","alg":"HS256"}" string(27) "{"typ":"JWT","alg":"HS256"}"

and Shared Server respone
Call to undefined function App\\Http\\Middleware\\sodium_base642bin()

So is it because of Sodium extenstion?

@lcobucci

ext-sodium is required extension (as stated in the composer.json). Please make sure it is installed.

Is there any way to install in Shared Hosting usign Cpanel without terminal access?

@lcobucci

Owner

@amrishkakadiya sorry but I can't help you with that, it's been ages since I last used shared hosting. Try contacting them.

It's also important to note that copying vendor files from one place to another is a bit error-prone. Try to use composer install to detect any potential incompatibility.

Locking here as we discovered it's not related to the lib itself but the environment in which the library runs.
