the following message identifies the error: "Failed to parse value [fals] as only [true] or [false] are allowed." Unfortunately, I have no idea where to look. I'm grateful for any support. Thanks. IMPORTANT: I did not change the configuration before the error. (Maybe it's related to a version update?) ---

Have the error now in the `elasticsearch.yml` found. Probably I did not look closely enough before. Many Thanks. ---
