Error message

Error while de/se values: {0}

What it means

FrontendError::ValueEncodingError, converted from ValueEncodingError: encoding or decoding a datum with the value-encoding layer failed while planning or manipulating plan data. Indicates a value that cannot be represented in the internal encoded form.

Solutions

  1. Inspect the underlying ValueEncodingError for the specific datum that failed to serialize/deserialize.
  2. Ensure values match the declared column types in the schema.
  3. Check for corrupt or stale encoded data from an older schema version.
