Upload button connected with dataset is rising an error "errorDescription: "No File To Upload"

Actually I am making a form over my client site where after filling the form completely user needs to pay a certain amount to submit the form data which is working fine but after payment status returns succeded then it will trigger the $w( ‘#formDataset’ ).save() here the error rises which say "errorDescription: “No File To Upload” I am confused that why it’s not working!.
Please kindly suggest me the solution for this problem.

Show us the code, we can´t answer it without it.

export async function payNow(event) {
 let paymentButton = $w('#pay');
 await createToken(encodeCard(createCard()))
        .then(async (token) => {
            console.log(token);
 if (token.id !== undefined) {
                console.log(payment);
 await charge(token.id, payment)
                    .then(async(chargeResponse) => {
 if (chargeResponse.status === "succeeded" || chargeResponse.status === "processing") {
                            $w('#agentAcademyAdvisorSubmissions').setFieldValues({
 'paymentStatuse': chargeResponse.status,
 'stripePaymentId': chargeResponse.id
                            })
 await $w('#agentAcademyAdvisorSubmissions').save().then(() => {
                                $w('#slideshow1').changeSlide(1).then(() => {
                                    $w('#box19').scrollTo()
                                })
                            })
                        } else {
                            $w('#loader').collapse()
                            paymentButton.label = "Pay Now";
                            paymentButton.enable();
                            $w('#err').text = chargeResponse.error.message;
                            $w('#err').show();
                        }
                    });
            } else {
                $w('#loader').collapse()
                paymentButton.label = "Pay Now";
                paymentButton.enable();
                $w('#err').text = token.error.message;
                $w('#err').show();
            }
        });
}


Here is the code please kindly check that out

@GiriZano??

The obvious question first: do you have anywhere on your form a file upload button? Second: if you press CTRL-i, you go into dev. console. Could you dump a screenshot from that error message here?
