One could possibly help diagnose if you attached your db.json to the issue

Hi @jdk1900 ,

Thank you for reaching out. It appears that you're encountering an issue where JSON Server is not recognizing a field with a numeric value (lastModified) as valid data. This is likely because JSON Server expects data to be structured as objects or arrays of objects. Standalone primitive data types like numbers or strings directly under the root are not supported by default.

To resolve this, you can encapsulate your lastModified field within an object. For example, instead of having: { "lastModified": 123456789 } You should structure your db.json like this: { "info": { "lastModified": 123456789 } } This way, lastModified becomes a property of an object, which is compatible with JSON Server's expected data format. If lastModified is meant to be a global property, you could name the enclosing object something like metadata or info.
