Log error and all data apart from Solcast says unknown

[DFIRBoo]

Added the custom component on Tuesday this week, no data has been pulled from Modbus as far as I can see and found this error in the log.
Latest version from HACS and using modbus TCP connection. No issues seeing data when using foxess_modbus.
I have tired re adding but the error in the log persists so not sure what the issue is.
