Allow overriding of lambda@edge origin-request for custom paths

[rdsedmundo]

Is your feature request related to a problem? Please describe.
I have a custom path on my NextJS app that I want to route through a custom Lambda@Edge function of my own, but this code overrides it even if I provide it in the input configuration.

Describe the solution you'd like
Allow the override to happen, I don't think it makes sense to have a configuration that gets overridden always.

Describe alternatives you've considered
Since I can't do this override I have to manually edit the default-lambda code using a custom script on the build.postBuildCommands.

Additional context

nextApp:
  component: '@sls-next/serverless-component@1.19.0-alpha.30'
  inputs:
    cloudfront:
      /custom-route/*:
        viewerProtocolPolicy: 'redirect-to-https'
        allowedHttpMethods:
          ['GET', 'HEAD', 'OPTIONS', 'PUT', 'POST', 'PATCH', 'DELETE']
        minTTL: 0
        maxTTL: 31536000
        defaultTTL: 0
        forward:
          cookies: 'all'
          queryString: true
        compress: true
        lambda@edge:
          origin-request: THIS_GETS_OVERRIDEN_WITH_THE_DEFAULT_LAMBDA_ARN

Currently looking for this too. I have a laravel API that I currently proxy through with a fetch request on /api/ to the execute but that way im currently running 2 lambdas (the nextjs lambda for /api) and the remote lambda. So its about 400ms roundtrip.

If I could override the cloudfront origin under /api directly I could hook in my api directly instead of proxying through 2 lambdas

Any updates on this or maybe some workaround?

I haven't actually had a look yet if this is possible with the new 3.6 version ill have a dig through the new documentation when i get a chance

@dphang any idea where would be a good start for looking at this for someone who has never looked under the hood in this repo?

@mattvb91 yes I think as mentioned in the OP,

serverless-next.js/packages/serverless-components/nextjs-component/src/component.ts

Line 647 in 828b9dd

cloudFrontOrigins[0].pathPatterns[path] = {

as mentioned is the code that sets up the CloudFront configuration. Or you can try to use the CDK deployer as it might provide more flexibility
