- Around line 213-215: The raised ImportError in the reader-loading block should
preserve the original exception context: replace the bare raise ImportError(...)
with a chained raise using the caught OptionalImportError (e.g., raise
ImportError(f"required package for reader {_r} ...") from e). Update the raise
in the block that references _r so the ImportError is raised "from" the caught
OptionalImportError to preserve the traceback.

Chain the exception to preserve traceback context.
The OptionalImportError should be chained when raising ImportError; otherwise debugging is hindered.
Suggested patch
except OptionalImportError:
- raise ImportError(
- f"required package for reader {_r} is not installed, or the version doesn't match requirement."
- )
+ except OptionalImportError as err:
+ raise ImportError(
+ f"required package for reader {_r} is not installed, or the version doesn't match requirement."
