Error: EISDIR illegal operation on a directory, open '{path to a dir in the zip file}'

Hi Folks,

I am facing this issue of illegal operation when I am trying to unzip a zip file which has multiple directories in it using decompress module.

Is it something related to the permissions of the particular zip file?

Sample Code:

var unzipFiles = async function (dirPath, dcmfolder) {
const files = fs.readdirSync(dirPath);
await Promise.all(
files.map(async (file) => {
const fullFilePath = path.join(dirPath, "/", file);
if (file.endsWith(".zip")) {
console.log("Inside unzip if condition");
await decompress(fullFilePath, dcmfolder);
}
})
);
};

Start by reproducing the sample code with a ZIP archive containing multiple directories and inspect how decompress handles directory entries. Confirm whether extraction attempts to open a directory as a file, then verify that archives with nested directories extract without the EISDIR error.
