SQL Command Timeout



We are receiving the following Uipath error when we run a stored procedure. It only occurs when the result set takes over 30 seconds to return. We have checked SQL timeout settings, execution etc. and they are set as expected.

Error and stack trace below.

Hi Thom!
Please check this post:


Connect Timeout is only for the connection.
In this case, this is command Timeout that should be increase, but it is not possible in the connection string nor in the Execute Query activity…


You will have to specify the command time out period explicitly for the SPs running for long time.
Use below code to build the connection and run a stored proc.
