API restrictions for drawing attributes

Hi All,

I created a NX drawing with an associated model and saved.  Through external integration that uses Siemens API, I tried to update one of the Part attributes in the drawing.  This update works fine if the length of the value is less than 133 characters. 

Small text updated using Simens API - Successful

If I update the field with text of length more than 133 chars, following error is displayed.

Error message displayed

Also the field is not updated.  It still retains the old value

On manually updating the field value in NX, it works.  Resized to fit text..

updating manually in PropertiesResized the box

Is there any option to overcome this API issue, when updated from external integrations?
