Invisibale Recaptcha is not working

[vocus-digital]

<div vc-recaptcha key="transacInfo.recaptchaPublicKey" on-create="setWidgetId(widgetId)" on-success="setResponse(response)" on-expire="cbExpiration()"></div> <div class="form-group txt-left">

Set vcRecaptchaServiceProvider.setSize('invisible');

I am not geeing widgetId which is 0 and vcRecaptchaService.getResponse() gives "" While if I use the same code for visible that works fine.
