Word Addin function - insertFileFromBase64 not working post September 22 updates

Question

Hi Team,

We have developed a word Addin to configure the templates. This Addin has capability to edit already existing templates by pulling them from repository and rendering them on MS word and to do so we are passing the byte stream to insertFileFromBase64(myBase64, "replace") to get the template document rendered.

Error: {"description":"InvalidArgument","name":"RichApi.Error","code":"InvalidArgument","traceMessages":[],"innerError":null,"debugInfo":{"code":"InvalidArgument","message":"InvalidArgument","errorLocation":"Range.insertFileFromBase64"},"httpStatusCode":400,"stack":"InvalidArgument: InvalidArgument\n at Anonymous function (https://appsforoffice.microsoft.com/lib/1/hosted/word-win32-16.01.js:25:307762)\n at Anonymous function (https://appsforoffice.microsoft.com/lib/1/hosted/word-win32-16.01.js:25:236859)\n at I (https://appsforoffice.microsoft.com/lib/1/hosted/word-win32-16.01.js:25:236835)\n at D (https://appsforoffice.microsoft.com/lib/1/hosted/word-win32-16.01.js:25:236708)\n at h (https://appsforoffice.microsoft.com/lib/1/hosted/word-win32-16.01.js:25:235204)"}

This Addin was working fine and the error started popping up recently after September 22 updates.

Answer 1

Are you talking about dotx or dotm templates?

If so, why don't you use Documents.Open to open the template and have code make whatever modifications are required to it?

Answer 2

Hi Doug,

No these are not dotx or dotm templates, these are documents which can be modified using addin.

Answer 3

Hi Albert,

Addin works in office 365 though it facing issue in Word 16 Standard version. In safe mode, we don't have option to load the addin.

Answer 4

Hello Dheeraj,

Thanks for reaching out here regarding this query.

It seems that the Add-in itself isn't compatible with the recent update you installed in September.

Is this Add-in applicable in Word online?

Does the Add-in work in Word's Safe Mode, normally?

I will be able to use the relevant feedback information you provide to better see how I can help you with the experience you're having. Thank you!

Warm regards, Albert
