Question

He configurado una nueva configuración de WSO2 API Manager integrado con WSO2 Identity Server. Al iniciar el Administrador de API de WSO2, empiezo a recibir el siguiente error:

¿Alguien tiene alguna idea, por favor?

Answer 1

Esto podría suceder si la indexación no se ha realizado correctamente. Puede intentar rehacer la indexación de la siguiente manera.

1. Realice una copia de seguridad de la carpeta solr que reside en / solr y elimínela de la ubicación principal de API Manager.
2. Abre /repository/conf/registry.xml
3. En indexingConfiguration tag hay un valor llamado lastAccessTimeLocation. El valor predeterminado es

/_system/local/repository/components/org.wso2.carbon.registry/indexing/lastaccesstime

Cambia ese valor a

/_system/local/repository/components/org.wso2.carbon.registry/indexing/lastaccesstime1

4. Comience el servidor
