I'm unable to import saved objects (test.ndjson)from Kibana- 7.8.0 to Kibana-8.1.0, getting below error:
Sorry, there was an error
The file could not be processed due to error: "Internal Server Error"
No error captured in kibana log file.
Tried restarting Elasticsearch and Kibana, but didn't help.
Verified the JSON format for test.ndjson, its well formed JSON.
Please suggest how to address this error.
