SOLR error importing statistics

[Andrew K]

Hello!

I am trying to import statistics from 7.6 to 7.6.1 server and getting this error

# /dspace/bin/dspace solr-import-statistics
No index name provided, defaulting to "statistics".
Exception: Error from server at http://localhost:8983/solr/statistics: Server error writing document id 4c6a127a-31e0-46c3-9a11-21c289848623 to the index

There's a similar thread https://groups.google.com/u/2/g/dspace-tech/c/GshVU2RXE8w/m/FTUL2eCWBQAJ

But in my case it says nothing about very long strings, just error

Any help would be appreciated.

Thank you!

WBR,
