Invalid uri stat chart type:

Error message

Invalid uri stat chart type: 

What it means

UriStatChartTypeFactory.valueOf looks up the type string in a prebuilt map of UriStatChartType instances and throws NoSuchElementException when the key is absent. It is a strict lookup: unlike enum valueOf it accepts custom type strings but must know them at registration time.

Solutions

1. Use a chart type string supported by this build (check the keys registered in UriStatChartTypeFactory).
2. Align frontend and backend versions so both know the same chart types.
3. Handle NoSuchElementException in the controller and return a 404/400 listing valid types.

Example fix

// before
UriStatChartType t = factory.valueOf("bogusType");
// after
UriStatChartType t = factory.valueOf("cpu"); // a registered type key

UriStatChartType t = null; /* pre-check against the registered keys of uriStatCharts if exposed, else use try-catch */

try { t = factory.valueOf(type); } catch (NoSuchElementException e) { t = defaultChartType; }

When it happens

Trigger: Calling valueOf with a type string never registered in the factory's uriStatCharts map (or a typo / different case).

Common situations: Frontend sending a chart type parameter the backend version doesn't support; version mismatch between web UI and uristat-web module; renamed chart types.

Understand the failure class

Background: Invalid enum value errors: "Unknown type", "Invalid scope", "must be one of" — when a string is not on the library's allowed list — this error's family across 23 libraries.
