index-authority java.lang.NullPointerException after upgrade 6.x to 7.4

[amtuan...@gmail.com]

Hello all

I am having troubles rebuilding the authority index after upgrading to 7.4 and now 7.5. When I run /dspace/bin/dspace index-authority I get an exception immediately. This used to work perfectly on our 6.x server. Any help is much appreciated. Thanks.

$ /dspace/bin/dspace index-authority

Initialize org.dspace.authority.indexer.DSpaceAuthorityIndexer

I was able to run the index-authority command successfully now with DSpace 7.5 and some changes to ORCID authority section in my local.cfg in case someone runs into the same issue.
