This issue may occur because of inadequate Permission to the Fields Value used while calling API.
Solution:

Please check your permission with respective to IBX and Account associated with your USER
While calling API, values passed for Request Parameters ( such as accountNo, IBX, etc ) should be having Access Permission with your USER
