forecast crashes on adding first Zambretti record to database

[Alan]

I have run weewx for many years on linux (now Almalinux 9.6). I have recently upgraded to 5.1.0.

I use a separate forecast (mysql database). Sincle the install the 9am Zambretti forecast has not been updated. If I delete the forecast/archive table it is recreated in an empty state

when weewx runs.

I get this error when it attempts to update:

If I manually add one (old) record to forecast/archive table it does not crash but it has never added a new Zambretti record.

It can obviously access the mysql databse OK as it recreates archive if it is dropped.

Suggestions please.

Thanks
