Is find no longer supported in 4.6? Getting errors when moving to 4.6 from 4.30. Thanks.

The "Find" sample is working fine, so looks like is still supported. Note that in version 4.20, these modules moved from esri/tasks to esri/rest (more info here). Perhaps you might need to update some references somewhere.
