Fail to run if -Button is excluded

[yokhoe]

When trying to create a section without including a button, it seems to fail to run.

[PrzemyslawKlys]

Can you provide example?

[yokhoe]

Sure. I could recreate it using your example.

$Section3 = New-TeamsSection -ActivityTitle "**Przemyslaw Klys**"
-ActivitySubtitle "@PrzemyslawKlys - 9/12/2016 at 5:33pm" -ActivityImage Add
-ActivityText "Climate change explained in comic book form by xkcd xkcd.com/1732" `
-ActivityDetails $Fact3, $Fact4, $Fact5, $Fact6, $Fact7, $Fact8, $Fact9, $Fact10, $Fact11

The output is something like this

I can't reproduce it:

Clear-Host

if ($PSEdition -eq 'Core') {
    Import-Module PSTeams -Force -SkipEditionCheck #-Verbose
} else {
    Import-Module PSTeams -Force

$Fact5 = New-TeamsFact -Name 'Other link example' -Value "[Evotec](https://evotec.xyz) and some **bold** text"
$Fact6 = New-TeamsFact -Name 'This is how list looks like' -Value "

    * another

$Fact7 = New-TeamsFact -Name 'This is strike through example' -Value "<strike> This is strike-through </strike>"
$Fact8 = New-TeamsFact -Name 'List example with nested list' -Value "
- One value
- Another value
    - Third value
        - Fourth value
"
$Fact9 = New-TeamsFact -Name 'List example with a twist' -Value "
1. First ordered list item
2. Another item
* Unordered sub-list.
1. Actual numbers don't matter, just that it's a number
    1. Ordered sub-list
    2. Another entry
4. And another item.
"

$Fact10 = New-TeamsFact -Name 'Code highlight' -Value "This is ``showing code highlight`` "
$Fact11 = New-TeamsFact -Name '' -Value "

### As you see I've not added Name at all for this one and it merges a bit with Fact 10

This is going to add horizontal line below. While this line is highlighed.

Hmm... let me get back to you. I am currently testing on VSCode in MacOS Mojave. I'll try to get on a Win10 workstation and test again. Perhaps there are some discrepancies. Thanks for getting back so quickly.

[PrzemyslawKlys]

I've added a simplified test (without button) - https://github.com/EvotecIT/PSTeams/blob/master/Tests/Send-TeamsMessage.Tests.ps1 and currently it's running as part of AzureDevOps on Ubuntu/Mac/Windows... we should know whether this is not working on any of the platforms.

[PrzemyslawKlys]

It indeed failed on Ubuntu, so probaly will fail on Mac. It worked fine on Windows.

I'll see what the problem is on Linux, but from what I see now it's a problem on PowerShell 6+.

[PrzemyslawKlys]

Ok, problem found. Sending new code, will publish soon.

[PrzemyslawKlys]

Please use

Update-Module PSTeams

Should fix your issue. It should also be faster to load as I've published as single psm1 (as per my article: https://evotec.xyz/powershell-single-psm1-file-versus-multi-file-modules/).

Thanks for reporting this.

[yokhoe]

Thanks for fixing. Should've checked my PSCore version.

[PrzemyslawKlys]

It wouldn't matter. The issue was that $null seems to be bad idea for PS6. PS5.1 was working fine with it. Simple fix :-)
