error index-discovery -b

[Matías Javier Saavedra Gajardo]

Hi dears.

I migrated a database from dspace 6.4 to dsapce 7.3, at the time of migrating I had no error, but at the time of indexing it gives me the following error.
It is appreciated if you help me to solve the error.

java.lang.NullPointerException

Hi Matías,

This error is likely to be related with a resource policy in your database that has a null eperson entry in the database. The null pointer exception is being thrown here: https://github.com/DSpace/DSpace/blob/79d70be6fb00cfb2f48f2f794ec188f511d6f1fe/dspace-api/src/main/java/org/dspace/discovery/SolrServiceResourceRestrictionPlugin.java#L119

Looks like it will be useful to create an issue ticket.

Best,

Agustina
