Add below code to NisApiId.java

/**
 * The /namespace/root/page API
 */
NIS_REST_NAMESPACE_ROOT_PAGE("/namespace/root/page"),

/**
 * The /namespace API
 */
NIS_REST_NAMESPACE("/namespace"),

/**
 * The /namespace/mosaic/definition/page API
 */
NIS_REST_NAMESPACE_MOSAIC_DEFINITION_PAGE("/namespace/mosaic/definition/page"),
