Unknown error

[dmlo]

Good morning OpenWhisk. I'm trying to hook up a test action to a Postgres database like so:

var conn = new NpgsqlConnection(connectionString);
var cmd = new NpgsqlCommand("INSERT INTO base_entity (name) VALUES ('danny')", conn);
cmd.ExecuteNonQuery();

I am getting this error message:

Connection string is verified ok. DB is operational. OpenWhisk will run the action if I comment out the 'ExecuteNonQuery' line.

Two questions:

1. Any idea where I've dropped the ball here?
2. Is there a way to get a more detailed error message?

Thank you for your time and I hope you're not too bored in quarantine.

In the end I was able to discover the error by using a try/catch block and outputting a string to Html.

Please see #39 for the error that was causing the action to fail
