{ "error": { "message": "(#135000) Generic user error", "type": "OAuthException", "code": 135000, "error_data": { "messaging_product": "whatsapp", "details": "Generic user error" }, "fbtrace_id": "AaaOcA7BW1O2ti_9duaR1c8" } }
there is no clue what cause this. when I try to send hello_world template it's working fine. but when using dynamic template got that error.
Trying send dynamic template without any parameter still got same error.
