[bug\_fix] ImportError: cannot import name 'Mapping' from 'collections' \(C:\\Python310\\lib\\collections\\\_\_init\_\_.py\)

Replace \`from collections import Mapping\` with \`from collections.abc import Mapping\` \(Python 3.3\+\). Alternatively, pin to an older version of the library that hasn't been updated for Python 3.10\+.

Journey Context:
Developer upgraded to Python 3.10 and ran an existing project. An import from a third-party library \(e.g., \`google-auth\` or \`requests\`\) failed with \`ImportError: cannot import name 'Mapping' from 'collections'\`. The error pointed to a line in the library's source using the deprecated \`collections.Mapping\`. The root cause: Python 3.10 removed the abstract base classes from \`collections\`; they now live in \`collections.abc\`. The fix: they upgraded the library to a newer version that uses \`collections.abc\`. If no update was available, they patched the import manually or used a compatibility shim.

environment: Python 3.10, pip 21.3, library version 0.8.0 that uses \`collections.Mapping\` · tags: importerror collections.abc deprecated python-3.10 compatibility · source: swarm · provenance: https://docs.python.org/3/library/collections.abc.html\#module-collections.abc
