pyparsing.ParseException: Expected end of text

The newest version of a cantools (4.0.0) crashes while parsing dbc on string: BA_ “BusType” “CAN”;

Error log:

Traceback (most recent call last):

File fragment:

BA_DEF_DEF_  "BusType" "CAN";
BA_ "BusType" "CAN";
BA_ "GenMsgCycleTime" BO_ 13 1;

Old, 1.0.0, works as expected.

Sorry, I was not able to answer your questions. In the nearest future, I’ll possibly again work with your amazing library and give you more feedback. Best regards, Alex

Closing since no response was received, and that usually means it works.
