Hi, Issue noticed for api gem compatibility which still looking older logstash core. I was tried to place 5.6.4 gem in vendor/cache still having problem. If we can sort logstash-core-plugin-api to 7.x i can rebuild with latest logstash core gem.
Could not find gem 'logstash-core (= 5.6.4)' in source at
./logstash-core or in gems cached in vendor/cache.
The source contains 'logstash-core' at: 7.4.0 java
