@Nitesh-vaidyanath if it is possible - please add a screenshot/query use use in Grafana for this ML model. This will help me a lot in reproducing bug and making app better.

Thank you a lot, V.

Thank you @Nitesh-vaidyanath for a details! It is in progress.

As a fast workaround you may try to use 0/previous in GROUP BY fill() expression. This should help.

Checked with LoudML schema - measurement with dots is good to go, so actual issue in my panel. It use bad converter for fill() values.

@vsergeyev Thanks for quick response. I tried replacing with 0 but still it is failing with below errors, i don't see this error when there is no dot in measurement name.
