Error in typescript but not javascript: TypeError: Cannot read property 'decode' of undefined #441
Description
I'm running into an issue where attempting to create a new SourceMapConsumer doesn't work in typescript but does in javascript. Tested with the following code:
const SourceMapConsumer = require('source-map').SourceMapConsumer
const rawSourceMap = {
version: 3,
file: "min.js",
names: ["bar", "baz", "n"],
sources: ["one.js", "two.js"],
sourceRoot: "http://example.com/www/js/",
mappings: "CAAC,IAAI,IAAM,SAAUA,GAClB,OAAOC,IAAID;CCDb,IAAI,IAAM,SAAUE,GAClB,OAAOA"
};
async function test() {
const whatever = await new SourceMapConsumer(rawSourceMap)
console.log('whatever is: ', whatever)
}
test()
In a js file, this logs a BasicSourceMapConsumer object. In a ts file, I get the following error
property 'decode' of undefined

I have encountered the same issue. It looks like something related to
whatwg-url.My workaround:
whatwg-urlto the latest version (in my case, 7.0.0 -> 13.0.0)After that, it works fine. But, of course, it is super hacky.
