TypeError: You may only yield a function, promise, generator, array, or object, but the following object was passed: "undefined"
co-debug/test/test.js function: foo
0: yield bar()
1: yield Promise.resolve()

Install
npm i co-debug
You may need to install co
by yourself.
Usage
node -r co-debug
Or add require('co-debug')
to your main file and make sure it's loaded before other packages:
require('co-debug')
const Koa = require('koa')
const app = new Koa()
app.use(function * () {})
Notes
co-debug
has some limitations
co-debug
only can tell:
- The function name that throws error
- The list of
yield
within the function - The file path that contains the function
Examples:
co-debug/test/test.js function: foo
0: yield bar()
1: yield Promise.resolve()
co-debug
may have trouble working with transpilers.
Only use co-debug
when needed
if (process.env.NODE_ENV !== 'production') {
require('co-debug')
}
const co = require('co')
// other stuffs
