Description

  • Source
JsPointerToString(NULL, 0, &str);

  • Expected str = empty string

  • Actual failed and returns JsErrorNullArgument

I think this should be possible

Research direction
Investigate the implementation of JsPointerToString in the ChakraCore source. The issue indicates that passing NULL with length 0 should return an empty string instead of JsErrorNullArgument. Look for the relevant code in the C API layer (likely in Jsrt.cpp or similar). The comments on the issue may have additional insights. Ensure the fix does not break existing behavior where NULL with non zero length should still error.
