BugFix(SDKError): Correct error formatting in SDKError __str__ method… #1588
Conversation
…#1587) ### BugFix: Correct error formatting in SDKError.__str__ #### Problem Calling `str(SDKError)` raised the following runtime error: `looker_sdk.error.SDKError: <exception str() failed>` This happened when the SDK attempted to convert the error to a string, which failed due to a malformed generator expression or naming conflict during the formatting of `self.errors`. #### Fix Updated the loop variable in the generator expression from `error` to `error_details` to: - Avoid potential name shadowing. - Improve clarity and correctness of the `__str__` implementation. - Resolve the runtime error so the error can now be printed correctly. #### Notes - The variable `error_details` represents a single instance; per PEP 8, we may later rename it to `error_detail` for readability.

Hello @drstrangelooker, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
Summary of Changes
Hello, Gemini/gemini-code-assist here to provide a summary of this pull request. This PR addresses a bug where attempting to get the string representation of an SDKError instance would fail with a runtime error (<exception str() failed>). The root cause was identified as a potential variable naming conflict or shadowing within the generator expression used to format the error details in the __str__ method of the SDKError class. The fix involves renaming the loop variable in this generator expression to resolve the conflict and ensure the error details can be correctly formatted into the final string output.
Highlights
- Bug Fix: Resolves a runtime error that occurred when calling
str()on anSDKErrorinstance, which prevented the error details from being properly formatted and displayed. - Code Change: Updates the loop variable name within the generator expression inside the
SDKError.__str__method fromerrortoerror_detailsto avoid a naming conflict and fix the string formatting issue.
Changelog
- python/looker_sdk/error.py
- Corrected variable name in
SDKError.__str__generator expression (error->error_details) to fix error formatting bug.
- Corrected variable name in

Code Review
This pull request effectively addresses a runtime error in the SDKError.__str__ method. The problem, as described, where str(SDKError) would fail due to an issue in formatting self.errors (likely a name shadowing conflict with the loop variable error), is resolved by renaming the loop variable to error_details.
This is a precise and important fix, as correct error reporting is crucial for SDK usability. The code change is clear and directly tackles the identified issue. Well done on diagnosing and fixing this bug!
The PR description is also very clear and helpfully includes a note about a potential future refinement for the loop variable name (error_details to error_detail) to align even better with PEP 8, which is a good observation.
Summary of Findings
- Loop Variable Naming Convention (PEP 8): The loop variable
error_detailsis used to iterate overself.errors, where each item is a singleErrorDetailinstance. While the current nameerror_detailssuccessfully resolves the bug, renaming it toerror_detail(singular) would align more closely with common Python (PEP 8) naming conventions for loop variables that represent a single item from a collection. This is a low-severity stylistic observation. It's excellent that this was already noted in the pull request description as a potential future refinement. Due to the review settings focusing on medium severity issues and above, a formal review comment was not added for this point.
Merge Readiness
The pull request addresses a significant bug and the fix is correct and well-implemented. The minor stylistic point regarding variable naming is already acknowledged by the author. The code is in good shape and ready for merging. As a reviewer, I cannot approve the pull request, but I recommend it for merging once any internal review processes are complete.

BugFix: Correct error formatting in SDKError.str
Problem
Calling
str(SDKError)raised the following runtime error:looker_sdk.error.SDKError: <exception str() failed>This happened when the SDK attempted to convert the error to a string, which failed due to a malformed generator expression or naming conflict during the formatting of
self.errors.Fix
Updated the loop variable in the generator expression from
errortoerror_detailsto:__str__implementation.Notes
error_detailsrepresents a single instance; per PEP 8, we may later rename it toerror_detailfor readability.
