Hi! I’ve managed to install a brand new XWiki 13.8 instance in this environment:
Apache Tomcat/9.0.45 MySQL Server version: 8.0.26 Source distribution mysql-connector-java-8.0.26.jar CentOS Linux release 8.4.2105 [rjr@e220i059h057w ~]$ java -version openjdk version "1.8.0_302" OpenJDK Runtime Environment (build 1.8.0_302-b08) OpenJDK 64-Bit Server VM (build 25.302-b08, mixed mode) [rjr@e220i059h057w ~]$
Somehow, the installation of a flavor (step 2) failed, and I ended up with an empty wiki. I found this line in catalina.out:
2021-10-09 21:25:59,753 [extension.index job group daemon thread - org.xwiki.extension.index.internal.job.ExtensionIndexJob@3d455216([extension, index])] WARN o.x.e.i.i.j.ExtensionIndexJob - Failed to get remote extension from repository [extensions.xwiki.org:xwiki:https://extensions.xwiki.org/xwiki/rest]: IOException: Invalid answer  from the server when requesting [https://extensions.xwiki.org/xwiki/rest/repository/search?start=300&number=100&q=]
I think I remember there is a way to force the whole process again without having to delete the database, but I don’t remember how! Please, could you help me?
I would like to reproduce and document the error if it appears again!
