Unhandled exception using SQL activities

## Description
I enabled the SQL activities for PostgreSQL and SQL Server.
As soon as I drag & drop the SQL Query activity the following exception is thrown:

> StackTrace:

After that, I can configure the activity and publish the workflow, but when I run it I see the message “Successfully started workflow,” yet no workflow appears in the instances list.

## Steps to Reproduce
Download and use solution from [Elsa Server + Studio example](https://github.com/elsa-workflows/elsa-guides/tree/main/src/installation/elsa-server-and-studio).
Configure with the following base packages: Elsa 3.4.2, Elsa.Sql 3.4.2, Elsa.Sql.PostgreSql 3.4.2, Elsa.Sql.SqlServer 3.4.2, Elsa Studio 3.4.0.
Configure code to UseSql:

Run in debug Elsa server
Drag & drop the SQL Query activity => Attached Exception.
