Problem with Item in autodiscovery

[seraph]

Hello,

I'm using zabbix in version 5.4.4 and i have an issue with autodiscovery.
Generated JSON file are OK and i have in it below example data:

{"data": [{"channelID": 1, "channelSystemID": "monitor"}, {"channelID": 3, "channelSystemID": "monitor2"}, {"channelID": 24, "channelSystemID": "monitor3"}]}

and issue appear when i try to add item.

in script for item i'm trying to get value according to channelID what works when i run that script.
When i set in item key channelStatus[{#channelID}]
i receive information:
Cannot create item: item with the same key "channelStatus[{#channelID}]" already exists.

Please help me what am i doing wrong.

Best Regards.

All examples seem to have the keys in uppercase, like {#CHANNELID}, I don't know if that is a requirement or if you could fix this in preprocessing

Hello,

i've changed all information to uppercase, in json file and in zabbix configuration
and i still receive this information
Cannot create item: item with the same key "channelStatus[{#CHANNELID}]" already exists.

i've got some new info from debuging zabbix

configuration Item prototypes in zabbix:
Name: Channel state for [{#CHANNELSYSTEMID}]
Key: channelStatusAPI[{#CHANNELID}]

and i still receive information:
Cannot create item: item with the same key "channelStatusAPI[{#CHANNELID}]" already exists.

I don't see you setting LLD macros anywhere... Have you pointed those {#CHANNELID} and {#CHANNELSYSTEMID} to correct json path?

Thank You cyber for this tip

i've add LLD macro and all works now.

How did you solve your issue?
Thanks

I just add LLD macro in autodiscovery configuration
i've put names that i have in json file according to variables used in item Key
