JS C@E publish error "ERROR: the Fastly API returned 503 Service Unavailable: ."

[JakeChampion]

Version

Fastly CLI version 0.36.0 (dd0b7d9)
Built with go version go1.16.6 linux/amd64

What happened

I ran fastly compute publish and expected the project to be published to the Fastly Service but instead came across this error:

fastly compute publish --service-id 79cgjkVGQd9Db0tdbBjGbP
✓ Initializing...
✓ Verifying package manifest...
✓ Verifying local javascript toolchain...
✓ Building package using javascript toolchain...
✓ Creating package archive...

SUCCESS: Built javascript package js (pkg/js.tar.gz)

✓ Initializing...
✗ Uploading package...

ERROR: the Fastly API returned 503 Service Unavailable: .

occasionally the error would be different and say something about a broken pipe (I can't replicate that error anymore though and didn't save the full error message)

Update: just in case it is useful to know, here are the sizes of the files being published:

 ls -la bin pkg
bin:
.rw-r--r--  82M jake.champion  2 Aug 15:08 index.js
.rw-r--r-- 342M jake.champion  2 Aug 15:08 main.wasm

pkg:
.rw-r--r-- 71M jake.champion  2 Aug 15:08 js.tar.gz

Hi @JakeChampion there does appear to be some size restrictions in place. These restrictions aren't currently documented and there is ongoing discussion regarding this particular issue. We'll update this ticket once we have some more feedback.

I found the limits on this page -- https://docs.fastly.com/products/compute-at-edge-billing-and-resource-limits#resource-limits

The limit is 50mb for uploading a package

Thanks @JakeChampion just working on a PR now to add error checking for the package size limit.
