Error: EISDIR: illegal operation on a directory, read

Do you want to request a feature or report a bug? A bug I think.

What is the current behavior?

I have an project which is a react native project called th_views.rn and in the project there’s a folder which is still a react native project named examples

Then I run npm run android in examples which run the react-native run-android. Then the error show:

file:  /my_porject_path/th_views.rn/examples/.
Error: EISDIR: illegal operation on a directory, read

which the code around is node_modules/metro/src/node-haste/DependencyGraph/ModuleResolution.js:

  buildCodeFrameMessage() {
    let file;

    try {
      file = fs.readFileSync(this.originModulePath, "utf8");
    } catch (error) {
      if (error.code === "ENOENT") {
        // We're probably dealing with a virtualised file system where
        // `this.originModulePath` doesn't actually exist on disk.
        // We can't show a code frame, but there's no need to let this I/O
        // error shadow the original module resolution error.
        return null;
      }

      
      // I add for show the folder
      console.log("file: ", this.originModulePath)
      throw error;
    }

And the folder which perform read on is: /my_porject_path/th_views.rn/examples/.

It’s strange that perform read on .. How can I debug or fix this. Thank you.

It seems like that the error occurs when I open Devtools.

I solved that according to the highest answer in this question https://stackoverflow.com/questions/61339968/devtools-failed-to-load-sourcemap-could-not-load-content-for-chrome-extension
