Failed to add pass error

[nakajimayoshi]

Upon generating the .pkpass from the file template, the iOS Simulator throws the following error instead of loading the pass:

Failed to add pass: 'file:///Users/dev/Documents/projects/pass/pass.pkpass' Error Domain=PKPassKitErrorDomain Code=1 "No data supplied" UserInfo={NSLocalizedDescription=No data supplied}.

I've used the code from the README to generate the .pkpass:

package main

import (
	"archive/zip"
	"bytes"
	"fmt"
	"io/ioutil"
	"os"

	"github.com/alvinbaena/passkit"
	"github.com/google/uuid"
)

func main() {

	c := passkit.NewGenericPass()

	field := passkit.Field{
		Key:   "key",
		Label: "label",
		Value: "value",
	}

	serial := uuid.NewString()

	fmt.Printf("pass id: %s\n", serial)

	c.AddHeaderField(field)
	c.AddPrimaryFields(field)
	c.AddSecondaryFields(field)
	c.AddAuxiliaryFields(field)
	c.AddBackFields(field)

	pass := passkit.Pass{
		FormatVersion:      1,
		TeamIdentifier:     "==TEAM-ID==",
		PassTypeIdentifier: "==Pass-Identifier==",
		OrganizationName:   "orgName",
		SerialNumber:       serial,
		Description:        "test",
		Generic:            c,
		Barcodes: []passkit.Barcode{
			{
				Format:          passkit.BarcodeFormatQR,
				Message:         "1312312312312312312312312312",
				MessageEncoding: "utf-8",
			},
		},
	}

	template := passkit.NewFolderPassTemplate("passes/mypass.pass")

	signInfo, err := passkit.LoadSigningInformationFromFiles("certs/passmaker.p12", "test", "certs/wwdr.cer")

	signer := passkit.NewMemoryBasedSigner()

	if err != nil {
		panic(err)
	}

	fmt.Print("Pass signed\n")

	z, err := signer.CreateSignedAndZippedPassArchive(&pass, template, signInfo)

	if err != nil {
		fmt.Println("Error creating archive:", err)
		return
	}

	fmt.Print("Archive Created\n")

	err = os.WriteFile("pass.pkpass", z, 0644)

	if err != nil {
		panic(err)
	}

	fmt.Print("Finished creating pass\n")
}

No certificate errors are being thrown, so I think it's safe to say it's not related to certificates/signing.

I'm using the the Generic.pass from Apple as a template, and replaced the values of the JSON with the above fields. I also printed the contents of the pass.json after it was loaded into memory and all the fields were filled out as they were supposed to be, but I still get this error.

If you extract the generated pkpass file (it's just a signed zip file) are all the files from the template folder present? are the files named and placed as per the Apple documentation?. This library doesn't actually check that the files in the folder are correctly named.

@alvinbaena Don't see the option to unzip the file. Is it possible to unzip without installing 3rd party software?

[alvinbaena]

Sure, you'd have to do it via the terminal with the unzip command. You can check how the command works with a quick search.

Here is the result of unzipping the .pkpass archive:

That is indeed weird. Does the same behaviour happen if you try to open the pass on a real device?

[nakajimayoshi]

Same result

Sorry for the late response, I've been a bit busy.

Please try following the new example provided by a community member, and see if the error changes or goes away:

c := passkit.NewBoardingPass(passkit.TransitTypeAir)

// Utility functions for adding fields to a pass
c.AddHeaderField(passkit.Field{
    Key: "your_head_key",
    Label: "your_displayable_head_label",
    Value:"value",
})
c.AddPrimaryFields(passkit.Field{
    Key: "your_prim_key",
    Label: "your_displayable_prim_label",
    Value:"value",
})
c.AddSecondaryFields(passkit.Field{
    Key: "your_sec_key",
    Label: "your_displayable_sec_label",
    Value:"value",
})
c.AddAuxiliaryFields(passkit.Field{
    Key: "your_aux_key",
    Label: "your_displayable_aux_label",
    Value:"value",
})
c.AddBackFields(passkit.Field{
    Key: "your_back_key",
    Label: "your_displayable_back_label",
    Value:"value",
})

pass := passkit.Pass{
    FormatVersion:       1,
    TeamIdentifier:      "TEAMID",
    PassTypeIdentifier:  "pass.type.id",
    AuthenticationToken: "123141lkjdasj12314",
    OrganizationName:    "Your Organization",
    SerialNumber:        "1234",
    Description:         "test",
    BoardingPass:         c,
    Barcodes: []passkit.Barcode{
