Version problems

We are trying to set up a docker installation with Fess 14.18 and Opensearch 2.19.0. The problem i that the installation fails with the message that the plugins are built for version 2.19.1.

If we use Opensearch 2.19.1 it says the same thing:
Plugin [analysis-fess] was built for OpenSearch version 2.19.1 but version 2.19.0 is running

Any thoughts on what the problem is?

analysis-fess version 2.19.0 is designed for compatibility with OpenSearch version 2.19.1. For more details, please refer to the Dockerfile.
