fix(file): Support column named type

[maxi297]

Addresses https://airbytehq-team.slack.com/archives/C03GD9SV36E/p1741359423619149

Basically, a user is having issue when the column name is the reserved word type. We can support that if we check the type of the value when we see the key type during the schema inference.

📝 Walkthrough

Walkthrough

The pull request updates the _fill_nulls method in the DefaultFileBasedStream class. The method now checks the type of each schema value: if the value is a string or list, it sets it to ["null", v]; otherwise, it recursively invokes _fill_nulls on the value. This modification enhances the handling of nested schema structures without changing the overall control flow.

Changes

File	Change Summary
airbyte_cdk/.../default_file_based_stream.py	Modified _fill_nulls to include a conditional: for string or list values, assign ["null", v]; for other types, process recursively to handle nested schemas.

359-362: The fix properly handles nested "type" schema values.

This change adds more granular handling of the "type" key within schemas. Now, it checks if the value is a string or list (common for type definitions) before adding "null" to it, or recursively processes nested objects if needed. This solves the issue with columns named "type" in the data, which was causing schema inference problems.

Nice approach to distinguish between different value types while maintaining backward compatibility. Recursively handling nested structures ensures the schema is properly nullable throughout.

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

‼️ IMPORTANT
Auto-reply has been disabled for this repository in the CodeRabbit settings. The CodeRabbit bot will not respond to your replies unless it is explicitly tagged.

• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
