In midPoint 4.8.2, the advanced search in the "Resource objects" of a resource does not work:
When searching for attributes in the resource, the search fails with a NullPointerException or midPoint does not find the attributes. Begin of the insertion

End of the insertion Begin of the deletion

End of the deletion The error is independent of:
Connector and Resource Configuration
Filter method (equal, =, endsWith, =\[distinguishedName\], =\[stringIgnoreCase\] etc.)
Attribute name from the resource schema (e.g. sAMAccountName, dn, cn...) Begin of the insertion

End of the insertion Begin of the deletion

End of the deletion The search for "attributes/name" and "attributes/uid" works, as these attributes do not come from the dynamic resource schema.

This can easily be reproduced in the resource objects view of the resource "**LDAP Server (OpenLDAP)"** on [https://demo.evolveum.com.](https://demo.evolveum.com/)

**Variant 1 (attribute not found):**

`attributes/first_name = "Michelangelo"`
`attributes/ri:first_name = "Michelangelo"`

Error message: `Path attributes/sAMAccountName is not present in type {http://midpoint.evolveum.com/xml/ns/public/common/common-3}ShadowType`

**Variante 2 (fully qualified attribute name):**

`attributes/(http://midpoint.evolveum.com/xml/ns/public/resource/instance-3#first_name) = "Michelangelo"`

Error message: `Cannot invoke "com.evolveum.axiom.lang.antlr.query.AxiomQueryParser$FilterNameContext.filterNameAlias()" because "filterName" is null` Begin of the insertion

End of the insertion Begin of the deletion



End of the deletion In the customer's use case the basic search is not an option as no complex queries can be executed this way. Begin of the insertion

End of the insertion Begin of the deletion



End of the deletion Would you please check this issue and provide a fix?
