Error executing GET query

Error message

Error executing GET query: 
{query.query}
{query.params}
{e}

What it means

A defensive wrapper inside AsyncSqliteStore's batch GET processing (abatch path): after TTL refreshes, the SELECT for one namespace failed at the aiosqlite driver level and the exception is re-raised as ValueError together with the failing SQL text and bound parameters. Common root causes: database file locked/corrupt, schema mismatch after upgrades, or invalid stored data.

Solutions

  1. Read the embedded query and params in the message to pinpoint the failing namespace lookup
  2. Retry after releasing concurrent writers or closing other connections to the SQLite file
  3. Re-run store setup/migrations if the items table schema predates current expectations
Defensive patterns

Strategy: try-catch

When it happens

Trigger: Thrown at libs/checkpoint-sqlite/langgraph/store/sqlite/aio.py:439 when the library encounters an invalid state.
