PowerShell Slack Function - powershell

Question

I am trying to write a PowerShell function to call a Slack webhook. I took the function from a Reddit post, but the function seems to be failing with a parse error. Also I removed the webhook.
Here is the code:
function Send-SlackMessage {
Param (
[Parameter(Mandatory=$true, Position=0)]$Text,
$Url = "https://hooks.slack.com/services/xxxxx",
# Parameters below are optional and will fall back to the default
$Username = "XXXXXXX",
$Channel = "XXXXXXX",
$Emoji = "XXXXXX"
)
$body = #{ text=$Text; channel=$Channel; username=$Username; icon_emoji=$Emoji } | ConvertTo-Json
Invoke-WebRequest -Method Post -Uri $Url -Body $body
}
and the error:
At line:12 char:67
+ ... y = #{ text=$Text; channel=$Channel; username=$Username; icon_emoji=$ ...
+
Missing '=' #{ text=$Text; channel=$Channel; username=$Username; icon_emoji=$ ...
The hash literal was incommplete.
+ CategoryInfo :ParserError (:) [], ParentContainsErrorRecordException
+ FillyQualifiedErrorId : MissingEqualsInHashLiteral

Where's the function name? You are missing a comma after the 2nd param, and have an extra comma after the last param.
function whatever ()
{
param (
[Parameter(Mandatory=$true, Position=0)]$Text,
$Url="https://hooks.slack.com/services/xxxxx",
# Parameters below are optional and will fall back to the default
$Username = "XXXXXXX",
$Channel = "XXXXXXX",
$Emoji = "XXXXXX"
)
$body = #{ text=$Text; channel=$Channel; username=$Username; icon_emoji=$Emoji } | ConvertTo-Json
Invoke-WebRequest -Method Post -Uri $Url -Body $body
}
