Code Inspection: Redundant 'await' expression

Reports redundant await usages, such as await await, or awaiting a non-promise result.
When the 'Report for promises' checkbox is checked, this inspection will also suggest removing 'await' before promises when applicable (in return statements, and with Promise.resolve/reject).
While this is not generally necessary, removing 'await' in such contexts gives you two problems.
The first one is that surrounding your code with try-catch and forgetting to add 'await' will change code semantics, and you may fail to notice that.
The second one is that not having explicit 'await' may prevent the V8 runtime from providing async stack traces.

Suppress an inspection in the editor

  1. Position the caret at the highlighted line and press Alt+Enter or click the Intention action icon.

  2. Click the arrow next to the inspection you want to suppress and select the necessary suppress action.
