The document couldn't be loaded


#1

We decided to move the Groupdocs viewer into an iframe to isolate your styles and javascript. Unfortunately I’m now getting this error message when I try to annotate the document:


The document couldn’t be loaded…

This is happening in the call to /document-annotatin/CreateAnnotation which returns the following error message:

{“message”:“Value cannot be null.\r\nParameter name: key”}

I have compared the request json between a working and non-working version and one does not have the connectionId property:

Working request json:
{“connectionId”:“d2b6303c-197d-415c-aaf0-db8a8dfcd6c2”,“userId”:“3f8b6a5375337dae”,“privateKey”:null,“fileId”:“Quick_Start_Guide_To_Using_GroupDocs.pdf”,“type”:2,“pageNumber”:0,“rectangle”:{“x”:466.7218779342723,“y”:47.51061032863849,“width”:0,“height”:0},“annotationPosition”:{“x”:767.1566197183099,“y”:57.51061032863849},“textRange”:null,“svgPath”:null}

Non-working request json:
{“userId”:“ee2b20fdb1981c8a”,“privateKey”:null,“fileId”:“565e5d9c-ccc2-45cf-b106-4ae4cd764ec6.pdf”,“type”:2,“pageNumber”:0,“rectangle”:{“x”:283.1288659793815,“y”:134.07216494845363,“width”:0,“height”:0},“annotationPosition”:{“x”:383.2886597938145,“y”:144.07216494845363},“textRange”:null,“svgPath”:null}

If the missing connectionId is the problem, do you know why this might be happening?
