-Theses are expected to show up in the log.
-Unfortunately, there is nothing I know of that can be done to avoid them or even mute them.
-They can be, however, safely ignored.
-
-To [converts the `.ftl` values into a JavaScript object](https://github.com/InseeFrLab/keycloakify/blob/main/src/bin/build-keycloak-theme/generateFtl/common.ftl)
-without making assumptions on the `.data_model` we have to do things that throws.  
-It's all-right because every statement that can fail is inside an `<#attempt><#recorver>` block but it results in errors being printed to the logs.
-
-# The pages take too long to load ?
-
-The problem of templates taking a long time to load only happens in the test environment, when you have a console logging all the above-mentioned `.ftl` warnings in real time. Logging all those warnings is what takes time. Once in production page load is way faster.
-
-If you run the docker container locally we acknowledge that the loading time is getting out of hand.
-We are [in the process](https://github.com/InseeFrLab/keycloakify/pull/63) of resolving this issue.
-
-In the meantime we recommend [to run the docker container as a background task](https://youtu.be/F29Z1GaH-jk).
+It's just noise, they can be safely ignored.  
+You can, however, and are encouraged to, report any that you would spot.  
+Just open an issue about it and I will release a patched version of Keycloakify in the better delays.
