# [Yandex DataLens] Referenced connection <connection_ID> cannot be loaded: access denied

`ERR.DS_API.REFERENCED_ENTRY_ACCESS_DENIED`

You do not have permissions to make the connection required to build the chart. To fix the error, request connection access:

* To view the chart, request the **Execute** permission.
* To view the chart and the source connection parameters, request the **Read** permission.
