@StrayDragon Hello there! I'm Dosu, a bot here to help you with bug fixes, answer questions, and guide you on becoming a contributor. Let me know how I can assist you with the dataset API issue.

The error you're encountering indicates that the indexing_technique field is required but is missing or not correctly provided in the request. In the Dify codebase, the indexing_technique field is validated to ensure it is present and matches one of the allowed values, which are high_quality or economy [1][2].

To resolve this issue, ensure that the indexing_technique field is correctly included in your request payload. It should be part of the JSON data sent in the data form field, as shown in your example. Double-check that the JSON structure is correct and that the indexing_technique is properly specified.

If the issue persists, it might be due to a bug in the validation logic or the way the request is being processed. You may want to review the implementation of the /update-by-file endpoint to ensure it aligns with the expected input format and validation rules.

To continue talking to Dosu, mention @dosu.
