BUG: Get-MgChat and Get-MgUserChat, -All or -pagesize gives "the limit of 50 for Top query has been exceeded."

[mbourgon]

Howdy! I just started trying to use MG cmdlets. I'm trying to get all my messages in the last week, from any chat I'm in.
However, I immediately ran into what appears to be a bug - only a max of 50 are supported. Unfortunately, I need all - I can't filter on LastUpdatedDateTime since that's when something about the channel was changed, not the last message. Which means I need to look at all chats. (if there's a way to just look at all messages, maybe that would work?)

PS> get-mgchat -all
Get-MgChat_List1: The query specified in the URI is not valid. The limit of '50' for Top query has been exceeded. The value from the incoming request is '100'.

PS> get-mguserchat  -UserId "my-user-id-guid-here" -pagesize 300
Get-MgUserChat_List1: The query specified in the URI is not valid. The limit of '50' for Top query has been exceeded. The value from the incoming request is '300'.
PS> get-mguserchat  -UserId "my-user-id-guid-here" -All
Get-MgUserChat_List1: The query specified in the URI is not valid. The limit of '50' for Top query has been exceeded. The value from the incoming request is '100'.

@mbourgon, this is a known limitation with some Microsoft Graph APIs - https://docs.microsoft.com/en-us/graph/paging?context=graph%2Fapi%2F1.0&view=graph-rest-1.0:

Paging behavior varies across different Microsoft Graph APIs. Consider the following when working with paged data:

• Different APIs might have different default and maximum page sizes.
• Different APIs might behave differently if you specify a page size (via the $top query parameter) that exceeds the maximum page size for that API. Depending on the API, the requested page size might be ignored, it might default to the maximum page size for that API, or Microsoft Graph might return an error.

Please specify a -PageSize 50 with the -All switch to fetch all items. i.e.,

Get-MgChat -All -PageSize 50

We will be dropping our default page size of 100 in #1224.

Closing as duplicate of #1224.

@peombwa thanks, that worked, thanks! It was so damn odd that just doing "-all" threw an odd error message, that I created this ticket. (plus, I needed to get all messages.) Appreciate the help, just trying to figure out how to keep others from having the same problem.
