Inconsistent JSON serialization error messages #99925
Description
Bug report
When you try to serialize a NaN, inf or -inf with json.dumps(..., allow_nan=False), the error messages are inconsistent, depending on whether you use the indent argument or not.
>>> json.dumps(float('nan'), allow_nan=False)
ValueError: Out of range float values are not JSON compliant
>>> json.dumps(float('nan'), allow_nan=False, indent=4)
ValueError: Out of range float values are not JSON compliant: nanThat is because if you don't use indent, the encoding is done in C code here,
but if you use indent, the encoding is done in pure Python code here, and the error messages are different between the two.
Your environment
- CPython versions tested on: 3.11.0
- Operating system and architecture: MacOS 12.6, Apple Silicon
