Error decrypting string using openpgp.min.js

Question

I was able to decrypt a string openpgp.min.js but I accidentally deleted my code when trying move it different dir. I have coded it again but when I try to call decrypt function by passing msg and passphrase I get error in console.

Error decrypting message: TypeError: Error decrypting message: e.getDecryptionKeys is not a function

Promise { <state>: "fulfilled", <value>: undefined }

my code is as below:

async function decrypt(msg, pass) {
    const privateKeyArmored = localStorage.getItem('privateKey');
    const passphrase = `${pass}`;
    let privateKey;
    
    if (pass === null || pass === '') {
        console.log('Password is Null');
        privateKey = privateKeyArmored;
    } else {
        console.log('Password is not Null');
        try {
            privateKey = await openpgp.decryptKey({
                privateKey: await openpgp.readPrivateKey({ armoredKey: privateKeyArmored }),
                passphrase
            });
        } catch (error) {
            console.error('Error decrypting private key:', error);
        }
    }

    try {
        const message = await openpgp.readMessage({
            armoredMessage: `${msg}`
        });

        const { data: decrypted, signatures } = await openpgp.decrypt({
            message,
            decryptionKeys: privateKey
        });

        console.log('Decrypted:', decrypted);
    } catch (error) {
        console.error('Error decrypting message:', error);
    }
}

I'm using : OpenPGP.js v5.9.0 - 2023-05-15

It should log decrypted value to console.
