ArcGIS JS Api 4.9 attachments not displaying

PaulGiard

I have a Typescript SPA using ArcGIS JS Api 4.9.  When I query the layer for attachments I receive a attachment info array with the correct values.  When I try and display the items in the array I receive undefined?

if (layer.capabilities.data.supportsAttachment) {

const attachmentQuery = {

objectIds: feature.getAttribute('OBJECTID')

};

layer.queryAttachments(attachmentQuery).then((attachmentInfos: esri.AttachmentInfo[]) => {

console.log('Attachment infos: ', attachmentInfos);

console.log('Attachment 0: ', attachmentInfos[0]);

for (let index = 0; index < attachmentInfos.length; index++) {

const element = attachmentInfos[index];

console.log('Element: ', element);

}

attachmentInfos.forEach((attachment) => {

console.log('Attachment: ', attachment.contentType);

});

});

}

The above code produces:

1. Attachment infos: [object Object]

   1. app-survey-survey-module.js (4677,17)

      [object Object]: {3: Array}

Oh sorry. I updated the app to use version 4.9. Here it is FeatureLayer.queryAttachments - 4.9 . 

foreach wont work because queryAttachments does not return array. It returns an object containing AttachmentInfo objects.
