Job Solr.CoreWatcher threw an unhandled Exception while trying to run Alfresco application

Question

I am trying to run Alfresco application (Alfresco 5.2) but for some reason I am getting this kind of error:

This is snapshot of my current environment which is working fine. I do not know what could be the problem here? The server starts at the end, but when I try to log in I cannot do that.

Looks like solr either has no access to the model cache dir or there are empty/corrupted model files. Please check that there are no 0-byte xml files in the solr model cache dir.

It helped, server starts without any errors in logs, but for some reason search still won't work. When I try to search I am getting error like this `ERROR [solr.core.SolrCore] [http-bio-8443-exec-7] org.apache.solr.common.SolrException: undefined field: "boolean@sd@{http://www.adama.com/model/document/1.0}documentStudyNotification" at org.apache.solr.schema.IndexSchema.getField(IndexSchema.java:1200)`. What could be the problem now? Thanks! @Heiko Robert – Mike1988B Mar 30 '23 at 07:50
I guess there are solr documents in your index which no longer have a model in your model cache dir. Try to reindex now following the procedure you describe in your other [question](https://stackoverflow.com/q/75875629/1898538) – Heiko Robert Mar 30 '23 at 08:05
so please just mark the answer as solution for the problem you described here – Heiko Robert Apr 04 '23 at 08:52
