Swagger UI is broken

While testing https://github.com/vorburger/www.fineract.dev/issues/11 and following the first links mentioned on https://www.fineract.dev, namely https://demo.fineract.dev/fineract-provider/swagger-ui/index.html (as well as https://demo.fineract.dev/fineract-provider/swagger-ui/fineract.yaml) I have noticed that the Swagger YAML and thus UI has recently been broken.

It's curious that the https://github.com/apache/fineract/blob/develop/integration-tests/src/test/java/org/apache/fineract/integrationtests/SwaggeruiTest.java did not catch this regression. It would be nice if this were addressed as part of fixing this. Would it perhaps suffice to add a GET /fineract-provider/swagger-ui/fineract.yaml (in addition to index.html) to that test? Or is it a (Docker) Container Image specific regression?

ptuomola or aleks or maybe Manthan perhaps digging into and finding a solution for this interests you, or you want to point anyone at this issue. (I won't be working on this, I'm just filing issues for what I find in the Fineract.dev logs.)
