cannot set custom field with array of options

[Al Sko]

with JIRA v7.1.9#71013  and JIRA rest API 4.0.0

Scala code:

case class JiraFieldDefinition(id: Long, fullIdForSave: String, typeName: String, itemsTypeIfArray: Option[String])

and then processing for custom fields:

case _ =>
  val fieldSchema = customFieldResolver.getId(fieldName)
  if (fieldSchema.isDefined) {
    val fullIdForSave = fieldSchema.get.fullIdForSave
    val valueWithProperJiraType = getConvertedValue(fieldSchema.get, value)
    issueInputBuilder.setFieldValue(fullIdForSave, valueWithProperJiraType)
  }

def getConvertedValue(fieldSchema: JiraFieldDefinition, value: Any) : Any = {
 fieldSchema.typeName match {
 case "array" if fieldSchema.itemsTypeIfArray.get == "string" => List(value).asJava
 case "array" if fieldSchema.itemsTypeIfArray.get == "option" =>
 List(
 new CustomFieldOption(fieldSchema.id, null, value.toString, Seq().toIterable.asJava, null)
 ).asJava
 case "number" => ValueTypeResolver.getValueAsFloat(value)
 case _ => value
 }
}

so, to summarize: this code goes through custom fields. it works fine for a custom "label" where an array of strings is expected.  ( case "array" if fieldSchema.itemsTypeIfArray.get == "string" )

but it fails for a custom field called "custom_checkbox_1" with ID 10102 and customId=customfield_10102.

(see the second "case"  for array+option).

the error I get is:

ErrorCollection{status=400, errors={customfield_10102=Invalid value '10102' passed for customfield 'custom_checkbox_1'.}, errorMessages=[]}

found a solution. had to use

ComplexIssueInputFieldValue.`with`("value", value.toString)

instead of

new CustomFieldOption(fieldSchema.id, null, value.toString, Seq().toIterable.asJava, null)
