code environment creation issue

Hi,

I am trying to create new env using python 3.8. with following packages

flatten-json
flask
dash

i have also included one custom library which needs python >3.8

When I am trying to use environment to create dash app, I am getting error -

AttributeError: module 'numpy' has no attribute 'bool'.`np.bool` was a deprecated alias for the builtin `bool`. To avoid this error in existing code, use `bool` by itself. Doing this will not modify any behavior and is safe. If you specifically wanted the numpy scalar type, use `np.bool_` here.The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at:    https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations

I tried to include numpy < 1.24 in environment

I am geeting error ERROR: No matching distribution found for numpy<1.24
