Unexplained esbuild error

[jaydenseric]

I'm struggling to figure out what the problem is with this URL:

https://esm.sh/react-waterfall-render@2.0.0/public/waterfallRender.js?target=deno

It result in a HTTP 500 status:

/* esm.sh - error */
throw new Error("[esm.sh] " + "unexpected esbuild output");
export default null;

Is this code not compatible with esm.sh, or is this a bug with the service? There isn't an obvious bundling error, as that package actually has a passing esbuild bundle test:

https://github.com/jaydenseric/react-waterfall-render/blob/fcbcb036f136a0c28d5ec551556ebac25040355d/test/bundle.test.mjs#L7-L26

I've tried the test with a bunch of esbuild versions (all passing) in case the esm.sh service hasn't deployed the latest one yet:

https://github.com/postui/esm.sh/blob/e65ba3e5cbccd27c9ad20f2817594830c121ae76/go.mod#L6

Skypack seems to deal with it fine:

https://cdn.skypack.dev/react-waterfall-render@v2.0.0/public/waterfallRender.js

Although it results in a runtime error that process is undefined, because skypack apparently doesn't do process.env.NODE_ENV based code elimination by default, which the react/jsx-runtime dependency contains:

https://unpkg.com/react@17.0.2/jsx-runtime.js

Here is the source in case something jumps out as being incompatible with esm.sh:

@jaydenseric thanks, i will look into it.

@ije what was the unexpected esbuild output, so I can investigate? Maybe it's something simple. I'm blocked at the moment.

Another clue; importing the same thing via the package index instead of a deep import appears to work:

- import waterfallRender from "https://esm.sh/react-waterfall-render@2.0.0/public/waterfallRender.js";
+ import { waterfallRender } from "https://esm.sh/react-waterfall-render@2.0.0/public/index.mjs";

We need deep imports to work though.

Getting desperate, so many packages I depend on have the same error. Here's another example:

https://esm.sh/graphql-react@15.0.0/public/Cache.js

I will fix it asap！
