Findings

• Created: 2024-03-19

Key Evidence

• User gets HTTP 500 with "not authorized [code: 7500]" error when importing SQL
• Root cause identified by commenter: SQL file contained BEGIN TRANSACTION and COMMIT; statements which are not supported in D1
• Documentation mentions this requirement but the error message is unhelpful
• Maintainer @RamIdeas asked (Jun 2024): "can the api provide a more helpful response than 'not authorized' when these keywords are used?"
• This is a D1 API issue, not a wrangler code issue

Recommendation

Status: CLOSE

Reasoning: This is not a bug in wrangler - it's a user error (using unsupported SQL statements) combined with an unhelpful API error message from the D1 backend. The root cause was identified in comments and the reporter's issue was resolved. The request for a better error message is a D1 API concern, not a workers-sdk issue.

Action: Close as not-a-bug with explanation. If better error messaging is desired, a separate issue should be filed for the D1 API team.

Suggested Comment

Closing this issue as it's not a wrangler bug. The "not authorized" error occurs when SQL files contain unsupported statements like BEGIN TRANSACTION and COMMIT; - D1 uses implicit transactions and doesn't support explicit transaction control.

The fix is to remove these statements from your SQL file as documented in the D1 import guidelines.

The request for a clearer error message is a valid enhancement for the D1 API team - if you'd like to pursue that, please file an issue in the appropriate D1/API repository or through Cloudflare support.
