Lab doesn't work with Benthos v3.2.1 (seems like it's Go 1.13) #18

I tried to build a lab with the latest benthos version (3.2.1) that requires Go 1.13.

It builds successfully with a few Dockerfile changes, but the Attempting to initialise Benthos engine... message doesn't disappear when I visit UI.

In the browser's console I see the following error:

(index):1 Uncaught (in promise) LinkError: WebAssembly.instantiate(): Import #20 module="go" function="syscall/js.copyBytesToGo" error: function import requires a callable
Promise.then (async)
(anonymous) @ editor.js:400

I noticed that whatever version of benthos I try to build with Go 1.13 in the lab I get the same error.

Looks like it's this: https://github.com/golang/go/issues/29827#issuecomment-455747409

Just need to remember that any time we upgrade the version of Go we also need to update the .js file that comes with it. I'll update later today and add comments on our docker images as a reminder for next time.

Looks like there's also a regression so we might not be able to upgrade to 1.13 until this is resolved https://github.com/golang/go/issues/34395

Looks like it's been patched up. Would love to have benthos lab up to date

Still getting LinkError: data segment does not fit in memory with Go 1.13.7.

DpoBoceka commented 4 years ago

Should we report the unexpected behaviour?

Jeffail commented 4 years ago

If we can dig into it more, I'm a little stretched right now so I'd rather not take this on right now.
