Description

Currently running forecast on a mable fails if any of the models errors out when being forecasted. Is there a way to either drop it completely or return some "NULL forecast" from such a model?

We run batches of 1000 models which take about 20 minutes to compute and then immediately the whole job fails with an error on just one bad model.

Basically, a feature similar to a bad model train function returning a NULL model instead of killing the entire process.

Research direction

Start from the forecast operation on a mable and compare its failure behavior with the bad-model train function described in the issue. Determine whether a failed model should be dropped or represented by a NULL forecast, then verify that one bad model no longer aborts a batch of forecasts.
