com.dropbox.core.ServerException: null when trying to get sharedListLinks

We're using dropbox-core-sdk - 5.1.1

To fetch existing shared links with the following code:

sharingClient: DbxUserSharingRequests
sharingClient
.listSharedLinksBuilder()
.withDirectOnly(true)
.withPath(path)
.start()

 Sometimes our requests failed with error:

com.dropbox.core.ServerException: null at com.dropbox.core.DbxRequestUtil.unexpectedStatus(DbxRequestUtil.java:394) at com.dropbox.core.v2.DbxRawClientV2$1.execute(DbxRawClientV2.java:154) at com.dropbox.core.v2.DbxRawClientV2.executeRetriable(DbxRawClientV2.java:330) at com.dropbox.core.v2.DbxRawClientV2.executeRetriableWithRefresh(DbxRawClientV2.java:351) at com.dropbox.core.v2.DbxRawClientV2.rpcStyle(DbxRawClientV2.java:137) at com.dropbox.core.v2.sharing.DbxUserSharingRequests.listSharedLinks(DbxUserSharingRequests.java:1597) at com.dropbox.core.v2.sharing.ListSharedLinksBuilder.start(ListSharedLinksBuilder.java:87) at com.kenshoo.kreative.clientlayer.dropbox.DbxSharingClientWrapperImpl.listExistingSharedList(DbxSharingClientWrapperImpl.scala:34) at
