Cannot execute powershell file with function call in Transact SQL script - tsql

Question

I have a problem with my Transact SQL script, I made a procedure in Transact SQL which has to execute a powershell script with a function. When I execute the file and method in the Command Prompt it works but if I put the command in Transact SQL it gives me an error saying that it doesn't recognize the command. I hope someone could help me.
Command Prompt command
powershell -command "& { . C:\Users\mslaats\Desktop\Databasescripts\Powershell\GmailLibrary.ps1; SendGmail "<email address>" "subject" "body" }"
Transact SQL script
PRINT 'Use the Divestar database'
USE [Divestar]
GO
PRINT 'Grant access to execute through a kind of cmd'
EXEC sp_configure 'show advanced options', 1
GO
RECONFIGURE
GO
EXEC sp_configure 'xp_cmdshell', 1
GO
RECONFIGURE
GO
-- Delete the old procedure
PRINT 'Drop procedure'
DROP PROCEDURE IF EXISTS [dbo].[SendEmail]
GO
-- Procedure --
PRINT 'Create procedure to send an email'
GO
CREATE PROCEDURE [dbo].[SendEmail]
#To VARCHAR(1024),
#Subject VARCHAR(1024),
#Content VARCHAR(1024)
AS
BEGIN
DECLARE #CMD VARCHAR(1024)
SET #CMD = 'powershell -command "& { . "C:\Users\mslaats\Desktop\Databasescripts\Powershell\GmailLibrary.ps1"; SendGmail "<email address>" "onderwerp" "bodytje" }"'
PRINT #CMD
EXEC xp_cmdshell #CMD
END
GO

After encountering this same problem, I've found out that I needed to check the ExecutionPolicy on both machines. I knew my ExecutionPolicy was fine on my machine, but I checked the SQL server machine via:
EXEC master..xp_cmdshell 'powershell -command "& { Get-ExecutionPolicy }" '
which returned Restricted (which means that no Powershell script can run, and hence I ran into the same error message that you did).
Additionally, I also made sure my script was stored in a location that SQL Server had permission to access. You could check this in your case with a command like:
EXEC master..xp_cmdshell 'powershell -command "& { dir C:\Users\mslaats\Desktop\Databasescripts\Powershell }" '
And that command will let you know if SQL can see your script or not. In my case, I put my script in a shared network location I knew SQL could already access.
