data was not an array

[Rahim T_S]

I'm trying to create an issue via rest API to out custom Jira and one of the custom field require an array as input

I didn't quite understand how to pass data as an array so I listed all the fields available and checked an existing issue by exporting it as xml

from listing all the custom fileds

  {

    "id": "customfield_15500",

    "name": "<redacted>",

    "custom": true,

    "orderable": true,

    "navigable": true,

    "searchable": true,

    "clauseNames": ["cf[15500]", "Test <redacted>"],

    "schema": {

      "type": "array",

      "items": "option",

      "custom": "com.atlassian.jira.plugin.system.customfieldtypes:multicheckboxes",

      "customId": 15500

    }

  },

and from the issue that was exported as XML

{
"customfieldname": "<redacted>e",
"customfieldvalues": {
"customfieldvalue": {
"__cdata": " Not Available in the list "
}
}
},

How it looked as XML

<customfield id="customfield_15500" key="com.atlassian.jira.plugin.system.customfieldtypes:multicheckboxes">

<customfieldname>redacted</customfieldname>

<customfieldvalues>

<customfieldvalue key="17163">

<![CDATA[ Not Available in the list ]]>

</customfieldvalue>

</customfieldvalues>

</customfield>

How can I add this custom filed using rest API ?



while I try I get

"errors":{"<redacted>":"data was not an array"}}


What is the general format of in jira for custom fields when data should be an array ?
