Hi @Elk_huh!

Another person who encountered a similar error found the mapping issue [via the instructions here](https://discuss.elastic.co/t/anomaly-detection-elastic-jobs-failing-to-start/220015).

Would you be willing to follow the steps suggested in the link above and post the output if those steps don't help resolve the error?
