Problem communicating with basecaller after MinKnow update

[gc-content]

Hello!

After installing the new version of the MinKnow (Installed version: 24.02.10, MinKNOW core: 5.9.7, Dorado: 7.3.9), readfish seems to be unable to communicate with the caller. Below I attach the stdout of readfish validate.

Adding a comment for anyone else reading this - we are aware of this issue and a fix is in progress. It results from a change in the underlying method of calling the base caller.
