you did a typo in your config, not sure where but you can probably use a yaml or json checker ... not sure which format was used in 1.12 anymore, but for anythin else bugwise, 1.12 is way way out of service :)

propbably a "," instead a "." or you edited a float number that is writen like 10.0 and omitted the "." and wrote 10 instead
