I've dowloaded the postman request's library. Using postman, I'm trying to make a request for bulk read of a custom module.

Using the Records->Bulk->Post request template as a starting point, I've changed the url to:

{{api-domain}}/crm/bulk/v2/read

In the body tag of the request, I've put the following:

{

}

After sending the request I've got:

{

    "code": "INTERNAL_ERROR",

    "details": {},

    "message": "Internal Server Error",

    "status": "error"

}

Also changed the module's name to "Cotizaciones" (custom module, also tried "CustomModule1" which was the name in API V1) and to "Contacts". In neither I've recieved a different answer.
