Error restore script json into rules based config

[curzon01]

Thanks for detailed description.

Actually this question was cause by unsuccessful attempts to recover devices. As this issue maybe also caused by additional bug of Tasmota let me just summarize what I've tested with regards to decode-config.

a.dmp file contains "script" b.dmp file contains "rules"

a.json:

{
    "script": ""
}

b.json

{
    "rules": ["", "", ""]
}

decode-config -s a.dmp --backup-file Out.dmp -i a.json
INFO: Load data from file 'a.dmp'
INFO: Backup successful to '.\Out.dmp' (Tasmota format)
INFO: Restore skipped, configuration data unchanged

decode-config -s a.dmp --backup-file Out.dmp -i b.json
INFO: Load data from file 'a.dmp'
INFO: Backup successful to '.\Out.dmp' (Tasmota format)
WARNING 9 (@5480): file '.\r.json' array 'rules' couldn't restore, format has changed! Restore value contains <class 'list'> but an array of size [3] is expected
Premature exit - #9 Restore data error
