getting wrong keys and auth value in webpush

i am using php web push to send notification but i am getting error.

it seems that generated keys and auth are not base64 encoded but even after encoding those value and trying to send notification i dont get notification.

is there any way i can check these values correctness.

i checked correctly with database entry and its easctly what is being sent.

i even tried base64_encode($string);

and even tried replacing _ - with + and \
