Problem:
Resolution:
This is a known issue that was fixed in Version 9.0.0. Upgrading to version 9.0.0 or newer will resolve the error.
The underlying cause is when a single-line entry field has the MAX-LINES property set. MAX-LINES is intended for use only with multi-line entry fields and should not be used with single-line entry fields. Removing the MAX-LINES property or setting MAX-LINES to 0 will also resolve the error.
