App not serving script #239

Closed jvluso closed 6 years ago

jvluso commented 6 years ago

I'm trying to run Aragon locally. When I do, the main aragon app cannot get the scripts from the other apps. The error being thrown by the main app in the browser is:

Failed to load Voting(0x9b061Cc570950952ccfD2B7df4c3B7FF94904e65)'s script (/script.js): Response { type: "cors", url: "http://localhost:3001/script.js", redirected: false, status: 500, ok: false, statusText: "Internal Server Error", headers: Headers, bodyUsed: false } index.js:2284

The error thrown by the app where it is running is:

Proxy error: Could not proxy request /script.js from localhost:3001 to http://localhost:3001. See https://nodejs.org/api/errors.html#errors_common_system_errors for more information (ECONNRESET).

Are you trying to run the app locally pointing to Rinkeby, or trying to run it locally pointing to testrpc?

Hey @jvluso, this sounds like a CORS / local dev server issue, which is weird.

A few questions, since there's a number of different things that could be going on:

Are the local apps on a fresh clone from the current master?
Which directory are you running the apps from, is it inside the app's app/ folder (e.g. you should be running npm run start in aragon-apps/apps/voting/app)?
Is localhost:3001 the aragon-apps/apps/voting/app server (hitting it should show just the voting UI)?
Which version of react scripts are the local apps' using? (Probably easiest is looking inside the app's app/'s package.json, e.g. aragon-apps/apps/voting/app/package.json; what's the entry for react-scripts?) Is it @aragon/react-scripts?
Does the app at app.aragon.one work for fetching scripts?

I am pointing at Rinkeby right now.
This is a fresh clone of master
I am running from aragon-apps/apps/voting/app
It is serving the html properly, and I can see the app, it just always says "nothing here" because the script isn't getting fetched
"@aragon/react-scripts": "^1.1.0-aragon.4"
Yes. When I point it at finance.aragonpm.com it works

Hmm, this is super super weird. Does http://localhost:3001/script.js give you anything back? Does app/public/script.js exist? Do any of the other local apps work or is it just Voting?

Otherwise, if it's working with <app>.aragonpm.com, I can only guess it's something funny with the webpack dev server that's used in our fork of react-scripts. Our fork has explicitly enabled CORS on it, so it shouldn't be a CORS issue :(.

Which OS are you running on? Most of us are using macOS, but maybe on windows or linux the dev server behaves differently / is buggy? Otherwise, you could try yarn if you haven't already, since the lock file might mitigate against any new updates in react-scripts' dependencies.

Script.js was being called Script.js.js. Renaming it solved the problem. This was happening on linux. Thank you for helping me.

Seems I have a CORS issue, reaching out to IPFS when following the tutorial (Bella 0.7). The Counter App doesn't show in the left pane, but it is listed as 'Unknown' when I follow the Permissions link

onbjerg commented 5 years ago

@marc4gov Seems like it's a bug in Aragon CLI. I think you'll find better answers there
