str.replace is not a function

Using this code:

 const options = {
                method: 'POST',
                headers: { 'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8' },
                json: true,
                uri: this.config.peachPaymentsUrl + `v1/checkouts`,
                body: {
                    'authentication': {
                        'userId': this.config.peachPaymentsUsername,
                        'password': this.config.peachPaymentsPassword,
                        'entityId': this.config.peachPaymentsAdhocPaymentChannelId
                    },
                    'amount': mathHelper.getCentsAsRandsString(cents),
                    'currency': 'ZAR',
                    'description': 'Ekaya VIP',
                    'paymentType': 'DB' } //debit
            };

const response = await request(options);

Gives the error str.replace is not a function. If I remove the headers line the error goes away.

You can see what is happening in the depths of the request-promise code:

Since you post form data try to use the form option like in this example instead of body and drop the 'Content-Type' header because it is added automatically then. Does this work?

Thanks, that works. But the problem is not that I’m using the API incorrectly, but rather when I do it gives me no error other than : ‘str.replace is not a function’ with no stack trace and no advice on what to fix. This bug is that the error isn’t handled properly and a message given to the user. That inner function shouldn’t be trying to call replace on something that isn’t a string.
