Why does AdmZip fail to zip throwing range error for a folder with size 525688 bytes?

Question

Edit: I think this is due to my vm running out of space. Also curious, when adm-zip writes into a new zip doesn't it remove the files from the local directory(soruce) and write them into Zip folder (destination) ?

I'm trying to zip a folder using adm-zip and running into the following error. Is this a known bug ? Or Am I doing something dumb ?

INFO    started zipping from source: /tmp/unzippedBuild/lambda to destination: /tmp/postBuild.zip

ERROR   RangeError [ERR_OUT_OF_RANGE]: The value of "value" is out of range. It must be >= 0 and <= 65535. Received 92171

My code looks like this:

exports.makeZip = function(source, destination) {
    console.info("started zipping from source: %s to destination: %s", source, destination);
    try {
        const zip = new AdmZip();
        zip.addLocalFolder(source);
        zip.writeZip(destination);
        console.info("done zipping");
    } catch (error) {
        console.error(error.stack)
        console.error("Zipping failed. Reason: %s", error)
        throw new Error(error.message)
    }
};

du command gives the following size.

525688  /tmp/unzippedBuild/lambda
