I've got this error message when I trying a script below:

Get-Process notepad | Search-Memory -Values @{
    Int = 1234, 5678
    String = 'Notepad'
} -OutVariable notepad

Of course, I executed notepad.exe at the time.

what's the problem??

I installed this with Install-Module -Name PSMemory and A(All to yes)

First, thank you for taking the time to open an issue and sorry for the inconvenience. This error is due to a typo in the struct definition I made earlier. I fixed that in bb69c92 but obviously forgot to update the module in the PowerShell Gallery afterwards. I did update it now so please try downloading version 1.1 and it should work then.

Nice! now it works by Install-Module -Name PSMemory -Force

PS C:\Windows\system32> Get-Process notepad | Search-Memory -Values @{
>>     Int = 1234, 5678
>>     String = 'Notepad'
>> } -OutVariable notepad

You're welcome. Tip: To get formatted/readable output of your search results pipe them to the Format-Memory Cmdlet afterwards.

Get-Process notepad | Search-Memory -Values @{…} -OutVariable notepad | Format-Memory

or

$notepad | Format-Memory

Alternatively, you can use the alias fm.
