JavaScript used await outside a valid async context
SyntaxError: await is only valid in async functions, async generators and modules
JavaScript found an await expression in code that is not an async function, async generator, or top-level module context.
Observed message
SyntaxError: await is only valid in async functions, async generators and modules
Why it happens
- Await is used inside a non-async function.
- Top-level await is used in code that is not treated as a module.
- A callback or loop body was converted to async logic without changing the function signature.
How to fix it
- Mark the containing function async when appropriate.
- Run the file as a module if top-level await is intended.
- Refactor synchronous callbacks so await only appears in valid async contexts.
