Error: spawn E2BIG when handling uploaded files

I have a simple function setup that accepts an uploaded file (that will later be moved to s3) but sandbox crashes with Error: spawn E2BIG right away.

[0] internal/child_process.js:366
[0]     throw errnoException(err, 'spawn');
[0]     ^

Steps to reproduce Steps to reproduce the behavior:

1. Any post function, mine has literally nothing in it but the default code generated from init.
2. Post a file to the path

Expected behavior Body data should contain the file contents

Additional context

Did some googlin’ and there might need to be a change to how sandbox passes data: https://stackoverflow.com/a/44091211

https://github.com/architect/sandbox/blob/master/src/invoke-lambda/spawn.js#L14

Should also mention we’re using: sandbox@1.4.3 architect@6.0.13 node v10.16.0 macos catalina

.arc

@app
testapp

@cdn
@static
fingerprint true

@http
get /
post /upload

@aws
profile testprofile
region us-east-1
bucket test-arc-upload

I also have this problem. Any progress on this?

Mainlined in Sandbox, and will be mainlined today in Architect 6.2.6.
