[ERROR]: Error clearing data definition with id=xx in FSUIPC_WASM.log ?

[SMN204]

MSFS2020  FSUIPC7 v7.5.1
Saw in FSUIPC_WASM.log:
[ERROR]: Error clearing data definition with id=14
.............................................................................................=15

There were no problems in the game.
And I see the same in FSUIPC_WASM_prev.log and there were no problems either!

What does this mean?

FSUIPC_WASM_prev.log FSUIPC_WASM.log

Those errors can safely be ignored - they are reported when the WASM is trying to clean-up after MSFS has quit, and the simconnect calls are failing as the connection is dead.
