A schema different from the one provided with the extension was detected.

It is recommended to use the schema.xml file shipping with the Meilisearch for TYPO3 extension as it provides an optimized field setup for using Meilisearch with TYPO3. A difference can occur when you update the TYPO3 extension, but forget to update the schema.xml file on the Meilisearch server. The schema sometimes changes to accommodate changes or new features in Apache Meilisearch. Also make sure to restart the Tomcat server after updating the schema.xml file.

Your Meilisearch server is currently using schema version {meilisearch.schema.name}, the recommended schema version is {recommendedVersion}. You can find the recommended schema.xml file in the extension's resources folder: EXT:meilisearch/Resources/Private/Meilisearch/. While you're at it, please make sure you're using the current meilisearchconfig.xml file, too.
