When making SQLite calls via https://esm.town/v/std/sqlite, occasionally the request fails with:

Error: {"statusCode":500,"error":"Internal Server Error","message":"fetch failed"}

• Platform: Val Town
• SQLite Library: https://esm.town/v/std/sqlite
• Original val: dcm31/github-leads-wizard

1. Open the HTTP endpoint for main.ts in this val
2. Make a POST request to trigger the SQLite INSERT
3. Observe the response

The SQLite INSERT should succeed and return { ok: true, id: "..." }

Sometimes returns:

{
  "error": "{\"statusCode\":500,\"error\":\"Internal Server Error\",\"message\":\"fetch failed\"}"
}

With stack trace:

at createResError (https://esm.town/v/std/sqlite?v=6:81:10)
at Object.execute (https://esm.town/v/std/sqlite?v=6:47:11)
at eventLoopTick (ext:core/01_core.js:179:7)

This error occurred in the github-leads-wizard val when:

1. User submits a company to analyze
2. createSession() is called which does an SQLite INSERT
3. The INSERT fails with the fetch error
4. This blocks the email results flow

See main.ts - it contains the minimal code to reproduce: just an HTTP endpoint that does a single SQLite INSERT.

• This appears to be a transient error (not always reproducible)
• May be related to cold starts or network timeouts
• The original code worked previously, suggesting infrastructure issue
