Laravel:在PDO对象上指定了不受支持的属性。 Ubuntu上的MSSQL

My Ubuntu vagrant Laravel Homestead set up has been configured to connect to MSSQL. Randomly it's starting throwing the following error on every query going to the MSSQL database (on a Windows server).

Any ideas? I can't find much info re:this available on Google.

I restarted PHP and confirmed SQLSRV modules are loaded.

SQLSTATE[IMSSP]: An unsupported attribute was designated on the PDO object. (SQL: select top 10 * from [orders] where [ordertype] = SO order by [orderdate] desc)

Check this issue report PDO::ATTR_PERSISTENT is not supported. Also they are reporting problems with PDO::ATTR_ERRMODE so check your connection for these two parameters.
