Greetings - is it possible to have nested dynamic mappings in your job?  When I try it, the op that's mapped to the inner dynamic mapping simply does not get executed with the following message
```Skipping step [inner_op_name] due to skipped dependencies: [].```
When I remove the outer dynamic mapping (by hardwiring it to run just the first element, not a long term solution), everything works fine

Actually a search through this channel's history seems to suggest that nested dynamic mappings are simply not supported.  Can you confirm this is actually the case?  I also think a better error message to indicate this would be great.

The best outcome, of course, would be to add support for this.  :slightly_smiling_face:

Hi, yes, we currently do not support nested dynamic mapping. We do have an issue to track this: <https://github.com/dagster-io/dagster/issues/4364>
