What happened?

Blob storage doesn't work:
GuzzleHttp\Exception\InvalidArgumentException: json_encode error: Malformed UTF-8 characters, possibly incorrectly encoded

How to reproduce the bug

Schema::create('blob', function (\Illuminate\Database\Schema\Blueprint $table) {
    $table->binary('blob');
});

$data = random_bytes(50);
$result = DB::table('blob')->insert([
    'blob' => $data,
]);

$newData = DB::table('blob')->first();

expect($result)->toBeTrue()
    ->and(DB::table('blob')->count())->toBe(1)
    ->and($newData->blob)->toBe($data);

Notes

No response

Potentially may have to mb_check_encoding($data, 'UTF-8'); and store it as blob if required.

I had a quick crack at it, but I'm getting a weird response from libsql.

turso-laravel/src/Database/TursoPDOStatement.php

Line 53 in f6501e7

'value' => base64_encode($value),

here it should be using base64, not value as per the HNANA docs.

I don't really have time to do a full investigation (and I don't even use turso), but should help you get started.

Hi @nick-potts, thanks for submitting the issue. This is a good catch. I've never encountered this issue since I haven't saved blob data in any of my database tables. I've confirmed that the issue is valid, and I'm working on it now.

PS: Thanks for the pointers!

I'm closing this issue for now since a permanent fix isn't coming soon. I've already merged a pull request with a quick fix into the main branch (See #4).
