Permission denied when using Deno.watchFs() relative path

[epomatti]

The following code will fail when running with deno run --allow-read=./src app.ts

const watcher = Deno.watchFs("./src");
for await (const event of watcher) {
  console.log(">>>> event", event);
  // { kind: "create", paths: [ "/foo.txt" ] }
}

Error:

error: Uncaught PermissionDenied: read access to "./src", run again with the --allow-read flag
    at unwrapResponse ($deno$/ops/dispatch_json.ts:43:11)
    at Object.sendSync ($deno$/ops/dispatch_json.ts:72:10)
    at new FsWatcher ($deno$/ops/fs_events.ts:15:16)
    at Object.watchFs ($deno$/ops/fs_events.ts:38:10)
    at file:///home/pomatti/projects/dumb-deno/app.ts:1:22

However if i change the first line of the script to use an absolute path it works fine:

const watcher = Deno.watchFs("/home/pomatti/projects/dumb-deno/src");

I guess Deno.watchFs() must allow relative paths when --allow-read is informed on startup?

Maybe you should use deno run -A to try it again ? Because it's possible needing other permission.

@zhanyuzhang if I put the absolute path it works, and also the initial error message says "read access". It is something to do with the fact that I specifying the path in --allow-read.

Paths should be resolved relative to CWD when creating new watcher. Looks like a bug.
