textModulesData[] is not being displayed

I have followed the codelad example but when viewing the pass in the wallet the textmoduledata information is not displayed.
this is my code:
`const genricClass = {
"id": ${issuerId}.${classSuffix},
"classTemplateInfo": {
"cardTemplateOverride": {
"cardRowTemplateInfos": [
{
"twoItems": {
"startItem": {
"firstValue": {
"fields": [
{
"fieldPath": "object.textModulesData['points']",
},
],
},
},
"endItem": {
"firstValue": {
"fields": [
{
"fieldPath": "object.textModulesData['contacts']",
},
],
},
},
},
},
],
},
},
}
const genericObject = {
'id': ${issuerId}.${order.nanoId},
'classId': ${issuerId}.${classSuffix},
"logo": {
"sourceUri": {
"uri": "https://storage.googleapis.com/wallet-lab-tools-codelab-artifacts-public/pass_google_logo.jpg"
},
"contentDescription": {
"defaultValue": {
"language": "en-US",
"value": "LOGO_IMAGE_DESCRIPTION"
}
}
},
"cardTitle": {
"defaultValue": {
"language": "en-US",
"value": "[SOLO PARA PRUEBAS] Google I/O"
}
},
"subheader": {
"defaultValue": {
"language": "en-US",
"value": "Attendee"
}
},
"header": {
"defaultValue": {
"language": "en-US",
"value": "Alex McJacobs"
}
},
"textModulesData": [
{
"id": "points",
"header": "POINTS",
"body": "1112"
},
{
"id": "contacts",
"header": "CONTACTS",
"body": "79"
}
],
"barcode": {
"type": "QR_CODE",
"value": "BARCODE_VALUE",
"alternateText": ""
},
"hexBackgroundColor": "#4285f4",
"heroImage": {
"sourceUri": {
"uri": "https://storage.googleapis.com/wallet-lab-tools-codelab-artifacts-public/google-io-hero-demo-only.png"
},
"contentDescription": {
"defaultValue": {
"language": "en-US",
"value": "HERO_IMAGE_DESCRIPTION"
}
}
}
}

const claims = {
  iss: credentials.client_email, 
  aud: 'google',
  origins: ['https://dev-api.hifumi.com'],
  typ: 'savetowallet',
  payload: {
    genericObjects: [genericObject],
    genericClasses: [genricClass]
  }
}`

and this is my result:

Start with the textModulesData and classTemplateInfo payload shown in the issue, then compare it with the codelab example and how the pass is rendered in Google Wallet. Verify the field paths and payload structure; the issue is done when the points and contacts text modules appear in the displayed pass.
