@dosubot[bot] commented on GitHub (Dec 12, 2025):

The TypeError happens because the detect_file_encodings function was recently changed to return a list of NamedTuples (FileEncoding) with attributes like encoding, confidence, and language, instead of dictionaries. However, the code in helpers.py still tries to access these as if they were dictionaries (e.g., encoding["encoding"]), which causes the error "tuple indices must be integers or slices, not str".

To fix this, update any code that accesses encoding["encoding"] to use attribute access: encoding.encoding. For example, change:

if all(encoding["encoding"] is None for encoding in encodings):

to

if all(encoding.encoding is None for encoding in encodings):

and similarly for any other dictionary-style access on FileEncoding objects.

This change aligns with how the output is used elsewhere, such as in markdown_extractor.py, and will resolve the TypeError. The root cause and the recent change are documented in PR #29022.

To reply, just mention @dosu.
