Hello, I have succefully deployed containers for both datahub-gms and datahub-front. They are both functional but when I log in, in the datahub-gms logs I get the following warnings and error:

I am using ElasticSearch 8.0.0. When I had ElasticSearch 7.9.3 (as in the quickstart docker-compose) I didn't get these messages.

It does seem to be some elasticsearch version error - we've not yet seen this yet but if there are major changes between 7.9.3 and 8.0.0 then its certainly possible

In the version there are a lot of changes, a few of them are related to the Bulk API. As the error I get is connected too with the Bulk API, it might be. But it is strange that no one has got this error before. Thanks anyways John.

@microscopic-mechanic-13766 Agree that is strange, though I'm not sure how many folks are actively using > 8.0 of elastic

True, but it seems like 7.9.3 might have the log4j vulnerability (at least later versions of ES have it) so for a production environment it is non-viable
