GENERIC_INTERNAL_ERROR

GENERIC_INTERNAL_ERROR

Error message

Invalid color index: ${index}

What it means

SystemColor.valueOf(index) maps a numeric index to a predefined system color; if no registered color matches the index it is treated as an internal invariant violation and throws GENERIC_INTERNAL_ERROR rather than a user-facing argument error.

Solutions

1. Only pass indices produced by the library's own color()/rgb() functions
2. Verify stored color values were not truncated to a smaller integer type
3. If hit via SQL, check the input expression feeding the color index

boolean ok = SystemColor.isKnownIndex(index);

When it happens

Trigger: Calling the internal ColorFunctions SystemColor.valueOf(long index) with an index not matching any system color (e.g. a corrupted or out-of-range color index decoded from stored data).

Common situations: Round-tripping color values through external storage that truncates or renumbers them; hand-crafted queries referencing color() output manipulated numerically.
