I set up a fresh Sitecore 9.1 with SXA on my local machine.
When rebuilding the indexes, I get the following messages:

All other indexs ran withoout errors/warnings.
Has anyone any idea what could be missing?
The schemas are populated.

If you have the same problems with the master index and the SXA master index, please refer to the answer of @Dawid Rutkowski
The issue with the core index is still current.

    I currently have a ticket open with Sitecore for a very similar issue. Will let you know the outcome.

  • I'm looking forward to hearing from you. I found a blog post where the author has the same problem, but has no solution yet, too. Jan 16, 2019 at 22:41

The errors you see on the sitecore_master_index and sitecore_core_index are not SXA related. SXA is not overriding Sitecore indexes any more, it is using its own indexes.

The last error related to a missing field:

'extension_t_pl_str' is not an explicit field and doesn't match a dynamicField

is caused by wrong Solr server configuration. You Solr schema is missing a dynamic field. Please edit managed-schema file manually and add a following dynamic field:

<dynamicField name="*_t_pl" type="text_general" indexed="true" stored="true"/>

This should solve your problems. Keep in mind that populating managed schema from Sitecore might not create dynamic fields for all of the languages you are using in your content. You might need to add some fields manually to the sechema file.

  • Your answer solves the problem with the SXA master index. I see that the items have a polish item version, but the instance has no polish language. The items that cause the issue in the general master index come with the SXA installation, so imho it is an issue of SXA. In the installation guide for SXA it says that you have to populate the SOLR Managed Schema, but it does not add your node while having items with a polish language version. I cannot remember polish being a standard language of Sitecore. Maybe some developer accidentally did not remove these versions. Jan 17, 2019 at 9:16
  • After clicking Populate Solr Managed Schema again and your node still being in the managed-schema, the error comes up again. Jan 17, 2019 at 9:28

    Of course, it will pop up again because populating schema will override managed-schema file (all manual changes are gone). This issue has already been fixed a few weeks ago (polish versions removed). Just wait for SXA 1.8.1. Jan 17, 2019 at 12:18
  • Just like I wrote, keep in mind that when you'll add custom translations for different languages (not only polish ones) populating schema won't help and you will still need to manually update managed-schema file. By the default Sitecore has hardcoded list of dynamic fields which will be created. This logic is not scanning item versions. Jan 17, 2019 at 12:20
  • Ok, that's an information I can work with. Is it possible that you have to restart solr in order to make schema changes work? The rebuild of the index ignored my changes until I restartet the solr service. Jan 17, 2019 at 12:51
