How can I increase the accepted code size limit?

Hey folks. I'm submitting a large line of code and I see this response:

"{\"stack\":\"PayloadTooLargeError: request entity too large\\n at readStream (/piston_api/node_modules/raw-body/index.js:155:17)\\n at getRawBody (/piston_api/node_modules/raw-body/index.js:108:12)\\n at read (/piston_api/node_modules/body-parser/lib/read.js:77:3)\\n at jsonParser (/piston_api/node_modules/body-parser/lib/types/json.js:135:5)\\n at Layer.handle [as handle_request] (/piston_api/node_modules/express/lib/router/layer.js:95:5)\\n at trim_prefix (/piston_api/node_modules/express/lib/router/index.js:323:13)\\n at /piston_api/node_modules/express/lib/router/index.js:284:7\\n at Function.process_params (/piston_api/node_modules/express/lib/router/index.js:341:12)\\n at next (/piston_api/node_modules/express/lib/router/index.js:275:10)\\n at urlencodedParser (/piston_api/node_modules/body-parser/lib/types/urlencoded.js:100:7)\"}"

Is there an easy out-of-the-box solution to this problem?

My case is that we're inserting arguments into existing code, and they can be large. For example, calling a method with an array of numbers of size 10^5.

BTW, I eventually fixed it with this hack:

entrypoint: ["/bin/sh", "-lc"]
command:
- |
sed -i "s/app.use(body_parser.json());/app.use(body_parser.json({ limit: '50mb' }));/" /piston_api/src/index.js
exec /piston_api/src/docker-entrypoint.sh

I think it would be cool to have this out of the box. I will probably send the PR itself ASAP.

Updated: I submitted a PR that does what I want: #742 . Now I can easily insert an env like this:

environment:
  PISTON_BODY_PARSER_JSON: 50mb
