Dear Shawn, Thanks for the info. You are right. I have pasted only the client side stack trace. I failed to check the solr logs. As I went over the logs I found out that the same fieldnames cannot be created again and again according to Solr 7.6.0. In Solr 7.2.1, it was not the case. Anyhow I'll create a separate mail thread to discuss this matter.
