Netlify: Request with GET/HEAD method cannot have body

Describe the bug

Hello,

I updated to kit 234 & auto adapter 13 this morning and upon deploying to netlify I ran into the attached issue.

After asking in discord and trying a few things i have been unable to resolve it.

I then created a reproduction using the skeleton starter and managed to confirm the issue again. This may very well be down to a breaking change in https://github.com/sveltejs/kit/pull/3384

Happy to give more info if need be!

I’ve tried all these variations:

1. Setting NODE_VERSION env variable in Netlify Dashboard UI to 14 and 16 (but not 17)

2. Setting Node version in netlify.toml to 14 and 16 (but not 17)

3. Setting netlify.toml:

[build.environment]
  AWS_LAMBDA_JS_RUNTIME = "nodejs14.x"

1. Setting netlify.toml:

[functions]
  node_bundler = "esbuild"

Currently my package.json has:

"devDependencies": {
		"@babel/core": "^7.16.10",
		"@babel/preset-env": "^7.16.10",
		"@sveltejs/adapter-auto": "1.0.0-next.12",
		"@sveltejs/adapter-netlify": "^1.0.0-next.40",
		"@sveltejs/kit": "^1.0.0-next.233",
		"@tailwindcss/forms": "^0.4.0",

Currently Netlify env in the UI has only:

AWS_LAMBDA_JS_RUNTIME = nodejs14.x

My deploy is here: https://61e989e221b6fd00070a45cd--excel-demo-012.netlify.app

Try this one

Also you dont need adapter auto and netlify one or the other is fine

I dont think your issue is related to this one btw, maybe it should be its own ticket if you cant resolve
