Hello,

I'm having problems initialising an array variable. When I run the flow it says I'm using a string value. Any ideas?

[
"MeetingAttendanceApprovedDate": { "type": "string", "format": "date-time" },
"Honorariaruleid": { "type": "string", "format": "uuid" },
"ContactId": { "type": "string", "format": "uuid" },
"RuleName": { "type": "string" },
"IsQualified": { "type": "boolean" }
]

Hello @hpayne1993,

It looks like you’re pasting a JSON schema into an Array variable. The Initialize variable (Array) action expects an actual array value, not a schema definition that's why it's being treated as a string.

If you just want to initialise it empty, use:

[]

If you want to add objects, it should look like:

To extract a value from the array later, use something like:

Hope that helps! 😊
