Hi! I’m running into an issue getting my function deployed. It works locally when I run ntl dev, but after running ntl build it doesn’t work, unless I delete the zip file it creates and re-run ntl dev.
If I run ntl build and then ntl deploy I see 0 public functions for my site.
Hitting the function locally from insomnia after ntl build and then ntl dev I see this in my terminal:
Request from ::1: POST /.netlify/functions/create-checkout
{"level":"error","message":"End - Error:"}

Response with status 500 in 3 ms.
My site is loving-benz-ece62b.netlify.app/, although thus far I’m still stuck at the local stage so I’m not sure how helpful that is.
My netlify.toml looks like
[build]
functions = ".netlify/functions"
My function is at .netlify/functions/create-checkout.js. I’ve replaced the file contents with a sample from netlify functions:create like:
// Docs on event and context https://www.netlify.com/docs/functions/#the-handler-method
const handler = async (event) => {
try {
const subject = event.queryStringParameters.name || 'World'
return {
statusCode: 200,
body: JSON.stringify({ message: `Hello ${subject}` }),
// // more keys you can return:
// headers: { "headerName": "headerValue", ... },
// isBase64Encoded: true,
}
} catch (error) {
return { statusCode: 500, body: error.toString() }
}
}
module.exports = { handler }
When I run ntl build it finds the functions:
Packaging Functions from .netlify/functions directory:
- create-checkout.js
If I delete the zip files that are created, then re-run ntl dev everything behaves as expected and I get this response back:
{
"message": "Hello World"
}
I found this post about functions not being recognized and updated my package.json scripts to have a build:lambda line, but it hasn’t made a difference afaict.
"scripts": {
"develop": "gatsby develop",
"start": "gatsby develop",
"build": "gatsby build",
"serve": "gatsby serve",
"clean": "gatsby clean",
"build:lambda": "netlify-lambda build .netlify/functions"
},
Pretty stuck on this, would love any help! Thank you
