java.lang.RuntimeException: java.util.concurrent.ExecutionException: java.net.SocketTimeoutExceptionCause
Due to a slowness to produce results from Elasticsearch, the request took longer than Bitbucket was expecting and it timed out the request. By default, Bitbucket sets a 5 seconds time out for waiting results from Elasticsearch.
Solution
Increase the code search timeout:
Edit <BITBUCKET_HOME>/shared/bitbucket.properties adding the following parameter:
plugin.search.search.http.socket.timeout=10
In this example we raised the timeout to 10 seconds. However this may vary accordingly to the size of your instance.- Restart Bitbucket.
