I am using Firebase functions to process credit cards through square. My function works great for successful card transactions. However, with card errors such as declined or incorrect cvv, I want to send that error context to the user. What happens with my current code I just get an error 500 from the cloud function. When I look at the function logs, it has an Unhandled error { Error: Bad Request... I can see the desired text in the log but this doesn't get passed to the front end. Here is my current code.
export const processPayment = functions.https.onCall((data, context) => {
squareSetup();
const request_params = data;
const idempotency_key = crypto.randomBytes(22).toString('hex');
const payments_api = new squareConnect.PaymentsApi();
const request_body = {
source_id: request_params.nonce,
amount_money: {
amount: Math.round(request_params.amount * 100),
currency: 'USD' as squareConnect.CurrencyType
},
tip_money: {
amount: Math.round(request_params.tipAmount * 100),
currency: 'USD' as squareConnect.CurrencyType
},
idempotency_key: idempotency_key
};
return payments_api.createPayment(request_body);
});
According to the api found here. I should get a response of an array of Error types. However when I use a catch on the api promise like this
return payments_api.createPayment(request_body).catch(err => console.log(err))
It is not that. Instead it seems to be a full error response

I can see the expected error response from the api under a property called text but I am unsure how to drill down to just that data
I was able to get the expected response by simply drilling down with
return payments_api.createPayment(request_body).catch((err) => console.log(err.response.text));
