ID:13720 VHDL Type Conversion error at <location>: can't determine type of object or expression near text or symbol "<text>"

CAUSE: In a Type Conversion at the specified location and near the specified text or symbol in a VHDL Design File (.vhd), you attempted to convert the type of an object or expression. However, Quartus Prime Integrated Synthesis cannot determine the original type of the object or expression because the object or expression has more than one possible type.

ACTION: Make sure the design clearly specifies the original type of the object or expression. For example, you can explicitly specify a type for an object using a qualified expression.
