Bug Report

System Information

• Operating System: Windows 11 Home - 10.0.22623 Build 22623
• AMP version and build date: 2.4.6.4 - 07/09/2023 18:02
• Build Spec: Mainline

I confirm:

• [x] that I have searched for an existing bug report for this issue.
• [x] that I am using the latest available version of AMP.
• [x] that my operating system is up-to-date.

Symptoms

• What are you trying to do? Allow AMP to set config for generic template within json file.
• What are you expecting to happen? AMP to set config setting using JPath lookup.
• What is actually happening? ('Nothing' is not an acceptable answer!) AMP is throwing error message, and config file is not changing.

Reproduction

Add the following lines to the appropriate part of the openRCT2 template At Greelan/AMPTemplates:openRCT2

This is the neccessary addition to metaconfig.json

    ,{
        "ConfigFile":"user-data/users.json",
        "AutoMap":true,
        "ConfigType":"json"
    }

This is the user-data/users.json file, which is the file that the settings should be set to.

[
    {
        "groupId": 0,
        "hash": "",
        "name": "Server"
    },
    {
        "groupId": 0,
        "hash": "",
        "name": ""
    }
]

Additional lines to config.json, settings show up, but settings are not being writen to file, JPath may be incorrect / not functioning properly.

    ,{
        "DisplayName":"User Name",
        "Category":"OpenRCT2 Beta Features",
        "Description":"User Name for first admin, this should be set inorder to mannage games. Your user name based off of name set ingame.",
        "FieldName":"UserName",
        "InputType":"text",
        "ParamFieldName":"$.[1].name",
        "Placeholder":"Admin Player",
        "EnumValues":{}
    }
    ,{
        "DisplayName":"User Hash",
        "Category":"OpenRCT2 Beta Features",
        "Description":"User Name for first admin, this should be set inorder to mannage games. Your user name based off of name set ingame.",
        "FieldName":"UserHash",
        "InputType":"text",
        "ParamFieldName":"$.[1].hash",
        "Placeholder":"159FFE6F65C528C581E7CE710DC02E15AA1E44B1",
        "EnumValues":{}
    }

Error Message from console log when settings are being change.

You don't need the . after the $ - so it should be $[1].name

~~Same log error~~ I got a different error this time.

Are you still working on this? If so I'll reopen. But the error you're getting seems to be because you are adjusting the existing generic template and broke the settings file connection.
