"Malformed UTF-8 characters, possibly incorrectly encoded" with uuid relations

[masterix21]

Hi dears,

i found the same error using Passport and uuid for user_id column.

Try yourself with:

Schema::create('oauth_auth_codes', function (Blueprint $table) {
            $table->string('id', 100)->primary();
            $table->uuid('user_id');
            $table->integer('client_id');
            $table->text('scopes')->nullable();
            $table->boolean('revoked');
            $table->dateTime('expires_at')->nullable();
        });

and next generate a token from /oauth/token.

So it seems that the issue doesn't come from the ->with call, as it works with tinker.

Is it possible that return compact('user'); tries to return a JSON? This should be visible from the error trace.

If so, you can override the ->jsonSerialize method in the model, to support the custom relations:

public function jsonSerialize()
{
    return array_merge(parent::jsonSerialize(), ['user_id' => User::decodeUuid($this->user->id)]);
}

I'm afraid relations won't be automatically converted in our current implementation.

You're right, compact return an array, and thus it's being displayed as JSON on the browser.

I tried to override the method without success.
I ended not displaying JSON, but I guess I could $hidden the user_id and the workstation_id in the Work Model.

@zJoul could you share your solution here before we close this issue?

[zJoul]

@brendt Of course, I just call my view in my controller :

return view('user.profile', compact('user'));

And if I need the id to be displayed, I just call

{{ $work->workstation->uuid_text }}

Althought I do not know about JSON representation

[brendt]

I'm going to close this issue, and refer to #14 for followup, we'll revisit the default uuid behaviour and serialisation of the binary fields for the next major version.

Did you manage to find a solution for this problem?

[masterix21]

@andreidmour sorry, no. I have changed package, without binary conversion.

i am using Uuid to for user. After submiting the form i get this error "Error encoding model [Koboaccountant\Models\User] with ID [790c48b8-3eb5-5a31-ad77-333d642ef5b1] to JSON: Malformed UTF-8 characters, possibly incorrectly encoded ◀"

What does your user class look like?

Did you add the $uuids protected field?

Did you append uuid_text and hide uuid from json serialization?

May be a good idea to open your own issue. This one is closed.
