Provide required information needed to triage your issue

I am facing an issue with PowerPoint.DocumentProperties. I have an Add-In meant to work with PowerPoint, Excel and Word. I took the default manifest.xml and added <Host> tags for both <OfficeApp><Hosts></></> (<Host Name="..."/>) and <OfficeApp><VersionOverrides><Hosts></></></> (<Host xsi:type="...">...</Host>).

I have a function I mean to use in both which extracts the document properties of each app:

export async function getProperties(propertyNames?: string | string[]): Promise<object> {

  let res = {};

 

  // Check which host the add-in is running in

  const host = Office.context.host;

 

  if (host === Office.HostType.Word) {

    await Word.run(async (context) => {

      const builtInProperties: Word.DocumentProperties = context.document.properties;

      builtInProperties.load(propertyNames);

      await context.sync();

      res = JSON.parse(JSON.stringify(builtInProperties));

    });

  } else if (host === Office.HostType.Excel) {

    await Excel.run(async (context) => {

      const workbookProperties = context.workbook.properties;

      workbookProperties.load(propertyNames);

      await context.sync();

      res = JSON.parse(JSON.stringify(workbookProperties));

    });

  } else if (host === Office.HostType.PowerPoint) {

    await PowerPoint.run(async (context) => {

      const presentationProperties = context.presentation.properties;

      presentationProperties.load(propertyNames);

      await context.sync();

      res = JSON.parse(JSON.stringify(presentationProperties));

    });

  } else {

    throw new Error("Unsupported host application.");

  }

  console.log(res)

 

  return res;

}

Currently this function works for Excel and Word, but for PowerPoint returns nothing. I've tried specific propertyNames like keywords and *, but everytime the object is empty.

Your Environment

• Host [Excel, Word, PowerPoint, etc.]: PowerPoint
• Office version number: ______
• Operating System: Windows 10

Steps to reproduce

1. Create a new Office Add-In using Yeoman with React template.
2. Copy over the above code.

Thank you for letting us know about this issue. We will take a look shortly. Thanks.

Never mind it seems to be something wrong with the json conversion of PowerPoint properties, just using the properties without json works as intended.
