Something is messed up with a prototype chain. This seems to be a compatibility issue with Node >= 15, the bridge and spdy as well:

• spdy, and spdy-fixes — works, but:
  • corrupts prototypes for HTTP server — some side effects that makes it impossible to run together, it must be exclusive one

UPD: found a way to use spdy-fixes conditionally, using same pair of servers
