request.json() should be it

although i did have an issue at one point and could only get it to return what i needed with

Hello, I enabled functions and Static Forms Pages Plugin. Now Cloudflare rewrites the Javascript in my static assets (replacing

.innerHTML="<form></form><form></form>"

.innerHTML="<form></form><form></form>"

by

.innerHTML="<form method="POST"><input type="hidden" name="static-form-name" value="null" /></form><form method="POST"><input type="hidden" name="static-form-name" value="null" /></form>"

.innerHTML="<form method="POST"><input type="hidden" name="static-form-name" value="null" /></form><form method="POST"><input type="hidden" name="static-form-name" value="null" /></form>"

.innerHTML="<form method="POST"><input type="hidden" name="static-form-name" value="null" /></form><form method="POST"><input type="hidden" name="static-form-name" value="null" /></form>"

.innerHTML="<form method="POST"><input type="hidden" name="static-form-name" value="null" /></form><form method="POST"><input type="hidden" name="static-form-name" value="null" /></form>"

). Obviously this breaks the JS + the computation of the integrity hash, and I don’t see the point of this rewrite as this file is completely unrelated to functions. Is there a config flag I missed?

I have a CF page and Im stuck. In one of my pages functions, I do:

import { jsPDF } from 'jspdf'

import { jsPDF } from 'jspdf'

and I ran

npm install jspdf

npm install jspdf

and my page function works fine locally. My package.json also mentions this dependency. But when I push to my github to deploy, I see in the cloudflare dashboard

ERROR] Build failed with 1 error:

the logs also mention

  You can mark the path "jspdf" as external to exclude it from the bundle, which will remove this error.
