This is my code snippet:

				const data = await document!.getFileData({
					// saves the document with annotations in it

Hi dcheli
Thanks for contacting us for support.
From the code, I see that it is not correct just directly passing the undefined xfdfString to the function getFileData. Instead of doing this could you please try:

  instance.Core.annotationManager.exportAnnotations().then(async (xfdfString) => {
    const data = await doc.getFileData({
      // saves the document with annotations in it

Thanks I see my error and I was looking at it tooo long and overlooked that :frowning: Sorry for posting such a rookie mistake.
