Failed Typescript validation error

Making Packs
1

I’ve successfully added a number of addFormula’s to my code using a combination of reused parameters and local parameters. On my latest formula, I’m getting a “Failed Typescript validation” on my execute statement but I’ve verified all my ParameterType’s are String and all my other POST api calls are also returning: resultType: coda.ValueType.String

Any suggestions would be appreciated

Here is the relevant code:

const usingParameter = coda.makeParameter({
…
const customerIDParameter = coda.makeParameter({
type: coda.ParameterType.String,
name: “customerid”,
description: “A unique string which all charges from the same customer share.”,
});
const billingEmailParameter = coda.makeParameter({
type: coda.ParameterType.String,
name: “billingEmail”,
description: “The email address of the customer to send an invoice to.”,
});
…
});

pack.addFormula({
name: “Update_Customer”,
description: “Update customer emails and invoicing type in ChargeDesk”,
resultType: coda.ValueType.String,
isAction: true,

parameters: [
customerIDParameter,
billingEmailParameter,
coda.makeParameter({
type: coda.ParameterType.String,
name: “contactEmail”,
description: “Primary contact email address”
}),
coda.makeParameter({
type: coda.ParameterType.String,
name: “chargeTiming”,
description: “Timing of client invoicing / charging”
}),
],

execute: async function ([customerid, billingEmail, contactEmail, chargeTiming], context) {
let response = await context.fetcher.fetch({
method: “POST”,
url: “https://api.chargedesk.com/v1/customers/” + customerid,
form: {
‘send_email_to’: billingEmail,
‘email’: contactEmail,
‘description’: chargeTiming,
},
});
return response;
},
});

Here is the error message I’m getting:

Solved the problem (thought don’t fully understand why it created this issue). It had something to do with the resultType. I ended up pulling out all the response code since this is just an update push, and changing my return to:

return “Done”;

Now that I have it at least building, I can go back and play with it later to try to figure it out.

It looks like you tried returning response which is a Promise.

Look at this example, they use return response.body.url;

It looks like @Ron_Gerrans3 was using await, so response would have been a FetchResponse, not a Promise. However a FetchResponse is not a string, and the execute function must return a string when you set resultType: coda.ValueType.String.

Thanks for the follow-up, still working through all of this
