readfish unblock-all Command Fails with AttributeError: number with MinKNOW v6.0.8

[ahfitzpa]

I encountered an issue when running the readfish unblock-all command. The command fails with an AttributeError, and it appears to be related to using a version of MinKNOW (v6.0.8) that may not be compatible with the current version of readfish. Below is the detailed output and traceback.

readfish unblock-all --device "MS00000" --experiment-name "Testing readfish Unblock All"

Output:
