Hi, I've just started having problems with more recent conda versions - looks like CONDA_JSON=True isn't working any more

curiously it still works for mamba

On reflection https://github.com/conda/conda/issues/12987 is a better place to log a bug as it's conda rather than miniforge There's obviously something a little amiss as

conda build

no longer works either (

conda-build

is OK though) I'm making life difficult for myself by having custom conda packages installed from s3 which, on low effort attempt, didn't work with mamba Anyway posting here in case it helps anyone out
