Expected an object key

What it means

After { or a comma inside an object, the parser expects a quoted key. Finding a colon, bracket, or other token there usually means a key is missing or a stray character slipped in.

Example

{ : "Ada" }

{ "name": "Ada" }

How to fix it

Add the missing quoted key before the colon.
