REST API broken?

Hello there,

Whenever I try to retrieve data from the API I get empty data sets. I created two customers for testing and when I GET @ index.php/api/customers with valid authorization the response contains an empty data array. Also, I can't create customers using the API @ index.php/api/customers with the request body looking like this:

{
"email": "[email protected]",
"name": "test test",
"currency_code": "EUR"
}

What am I missing?

Regards,
L. Behr

Note:
When I try to create a customer the response contains this:

[…] "message": "The given data failed to pass validation.",
"status_code": 500, […]

I am currently seeing the exact same thing.

When I try to fetch a customer directly from an ID (like '/api/customers/59') I get this:

"message": "get_class() expects parameter 1 to be object, null given",
"status_code": 500,
"debug": {
"line": 126,
"file": "/var/www/html/vendor/dingo/api/src/Http/Response/Factory.php",
"class": "ErrorException",
"trace": [
"#0 [internal function]: Illuminate\\Foundation\\Bootstrap\\HandleExceptions->handleError(2, 'get_class() exp...', '/var/www/html/v...', 126, Array)",
"#1 /var/www/html/vendor/dingo/api/src/Http/Response/Factory.php(126): get_class(NULL)",
"#2 /var/www/html/app/Http/Controllers/Api/Incomes/Customers.php(42): Dingo\\Api\\Http\\Response\\Factory->item(NULL, Object(App\\Transformers\\Income\\Customer))",

[...]

Ah, hold up. You need to pass the company_id (the ID of the company in Akaunting). Which, if you only have one, would be 1. So try /api/customers?company_id=1

I am also stuck with somewhat same issue, I am trying with vendors api
http://akaunting.example.com/api/vendors
with GET method returns :
{
"data": [],
"meta": {
"pagination": {
"total": 0,
"count": 0,
"per_page": 15,
"current_page": 1,
"total_pages": 0,
"links": []
}
}
}

I am expecting all the vendors info list here

When tried to fetch a specific vendor with id the same error mentioned above is thrown, Tried giving company_id
http://akaunting.example.com/api/vendors?company_id=1 return the same json output above mentioned
Please help me with this

error mentioned is : message": "get_class() expects parameter 1 to be object, null given"
