Research direction
Start with the linked minimal reproduction and compare pie-chart label behavior when type is spider versus other types. Reproduce the error with an empty formatter on G2Plot 2.3.26, then trace the relevant chart-label handling in the repository. Done means spider labels accept the empty formatter without an error and the existing behavior remains intact.
