an internal error occurred during: “Generating NED Documentation…”

Clash Royale CLAN TAG#URR8PPPan internal error occurred during: “Generating NED Documentation…”
When I tried to generate the Veins NED documentation. I got this error
"an internal error occurred during: "Generating NED Documentation..."."
java.lang.RuntimeException: unknown tag code 43, cannot create object
to represent it.
Even after I reinstalled omnetpp and veins, still have the same error. How can I fix it?
What is the relation to doxygen?
