Groovy code to remove value from an Insight object type attribute

[Mariano Redondo]

I have a Jira service management custom field that stores an Insight object. This object type has in Insight an attribute of type "Object", and I need to remove its value when the issue transitions to an specific status.

There is an Insight postfunctions that allows to do this, but due to bug JSDSERVER-8437 it does not work when there is only one object stored on the attribute (which is my case). So I´m trying to write a groovy code to do this, but I´m stock receiving this error message as result:

class com.riadalabs.jira.plugins.insight.common.exception.GroovyInsightException

GroovyInsightException: ValidationInsightException: Validation errors were found: rlabs-insight-attribute-93: ErrorMessage{i18nKey='rlabs.insight.i18n.constraint.violation.ObjectAttributeValueBean.MinOne.value', parameters=[], additionalMessage=null}; '

The constraint violation confuses me as the attribute I´m trying to clean has 0 to 1 cardinality (in fact I can manually remove its value perfectly). Here the code I´m using, I´ll appreciate if you can help me find what I am doing wrong.

int insightSchemaID = 1;
int jiraCustomFieldIDForAffectedObject = 13813; // Jira custom field (Insight type) that stores the Insight object
int insightAtributoID = 93; // The Insight object attribute Id which value needs to be removed

newObjectAttributeBean.setObjectAttributeValueBeans([]);

/* ------------------------------------------------------------------- */
// 6. Assign the attribute id to the object attribute
/* ------------------------------------------------------------------- */

// assign the id of the attribute (got in step 3)
newObjectAttributeBean.setId(objAttrib.getId());

/* ------------------------------------------------------------------- */
// 7. Object update
/* ------------------------------------------------------------------- */

objAttribute = objectFacade.storeObjectAttributeBean(newObjectAttributeBean);

Found the solution, no need to make an update, attribute value can be deleted directly through objectFacade.deleteObjectAttributeBean(objAttrib.getId())
