# [Yandex DataLens] Response processing timeout

`ERR.CHARTS.RUNTIME_TIMEOUT`

Response processing timeout has expired.

The error arises because DataLens doesn't have enough time to process and render the arriving data in the chart.

To fix the error, reduce the amount of data returned by your query: use filters, for example. Be aware of the [limits](../../concepts/limits.md) imposed on the number of rows in datasets.
