IndicatorKeyAndValueProvided

Both a key and a value were provided to the data-indicator attribute.

The data-indicator attribute must have either a key or a value, representing the name of a signal. The signal will be assigned the value true when an SSE request is in-flight, otherwise it will be false.

Example:

1<div data-indicator-foo></div>

Alternative syntax:

1<div data-indicator="foo"></div>

See the docs for the data-indicator attribute.
