setValue not working in Safari browser

[Mahad28]

this.api.element('css selector', '#credit-card-frame', (result) => {
const frameWebElementId = result.value;
this.api.frame(frameWebElementId);
this
.setValue('@creditCardNumberInput', cardNumber)
.setValue('@creditCardSecurityCodeInput', securityCode)
});
this.api.frameParent();

return this;

Can anyone help me in this as the first setvalue after frame is not working on Safari.
