Describe the issue

version ： 0.9.0 During the process of generating and retrieving a CSV, it was found that it could not be executed normally, whereas the text generation worked fine.
在进行csv的生成检索中，发现不能正常执行，text是可以正常生成的。

The command used:
poetry run poe index --root indexs/ragtest_csv

The settings.yaml file was modified with the following configuration:

input:
  type: file
  file_type: csv
  file_pattern: ".*\\.csv$"

The error message is:

debug error：

Have you solved this problem? I also encountered the same problem, especially when the number of columns in the csv file exceeds 2, how should the text_column configured in setting.yaml be written?

We have a docs page detailing how to configure the input columns. I highly suggest moving to a newer version though, as we continually update the docs to reflect the latest and don't provide much support for prior versions.
