Cannot read properties of undefined (reading 'signerKeyPassphrase')

[Gangadhar9848]

##macOS Venture 13.5.2

nodejs: v18.18.0

Description

Wrote a simple program to see the Apple pass generated but got this error ": Cannot read properties of undefined (reading 'signerKeyPassphrase')" even though that attribute has been given as a string under certificates

Expected behavior

Should be able to read all certificate params required to generate apple pass
-->

Steps to reproduce

// Specify the file path
const filePath = './model/Generic.pass/pass.json';
const iconpath = './model/Generic.pass/icon.png';
const thumbnailpath = './model/Generic.pass/thumbnail.png';

// Create a new PKPass instance
    const pass = new PKPass({
    "thumbnail.png" : fs.readFileSync(thumbnailpath),
     "pass.json": fs.readFileSync(filePath),
     "icon.png": fs.readFileSync(iconpath),
      certificates: {
        wwdr: fs.readFileSync("./certs/wwdr.pem"),
        signerCert: fs.readFileSync("./certs/signerCert.pem"),
        signerKey: fs.readFileSync("./certs/signerKey.pem"),
        signerKeyPassphrase: "test"
    }
    });

Were you able to verify it by using (and changing) the examples?

Yes

If yes, which changes did you apply?

yes the way certificates can be read

Hi @Gangadhar9848, thanks for using passkit-generator!
I've edited your post because the code you provided was hidden.

You are using the API in the wrong way. You should not have a property certificates, which only belongs to PKPass.from.

Please look again at the API Documentation in wiki and the examples.

Feel free to come back to ask if you need any further help.

Let me know.

ah yes, I overlooked it. Thanks @alexandercerutti. Fixed it, pass has been generated but unable to open. need to check

If you need, you can use the guide in the wiki to help you debugging 💪

Thank You for this @alexandercerutti , I am able to create my first ever wallet pass:). i am new this so have a question. can this pass be opened in any apple device? i mean cant we assign to the user meant to be? may be i am missing to read that property somwhere

[alexandercerutti]

Apple Wallet passes can be opened on iPhones and Macs, but they depend on the loaded assets.
For example, to open a pass on an iPhone that uses a x3 resolutions assets, you will need (mandatory) an icon@x3.png file. I think that opening them on the Mac requires just the basic icon file, but I'm not sure.

They are zip files and do not own opening-protection mechanisms.

But, if you want, you can prevent sharing them.
