BUG

Hey everyone,

Found a bug in v2026.1.3 with -FilterType autocomplete (and -FilterType select) on a New-UDTableColumn when used inside a New-UDDynamic with -LoadData.

The error:

TypeError: Cannot read properties of undefined (reading ‘forEach’)
at filters.js:209:19
at Object.autocomplete (filters.js:207:16)
at Filter (utilities.js:101:62)
at dynamic.jsx:17 ← PSU’s own Dynamic component
To reproduce:

Apply the autocomplete filter and select a value
Click any button that calls Sync-UDElement on the parent Dynamic
React crashes
Minimal repro — paste this into a new page:

$Pages += New-UDPage -Name ‘Bug Repro’ -Url ‘bug-repro’ -Content {

$Cache:BugReproData = @(
    [PSCustomObject]@{ COMPANY_NAME = 'Contoso Ltd';    NAME = 'John Smith';  ID = '001' }
    [PSCustomObject]@{ COMPANY_NAME = 'Contoso Ltd';    NAME = 'Jane Doe';    ID = '002' }
    [PSCustomObject]@{ COMPANY_NAME = 'Fabrikam Inc';   NAME = 'Bob Jones';   ID = '003' }
    [PSCustomObject]@{ COMPANY_NAME = 'Fabrikam Inc';   NAME = 'Alice Brown'; ID = '004' }
    [PSCustomObject]@{ COMPANY_NAME = 'Northwind Corp'; NAME = 'Charlie Day'; ID = '005' }
)

# Clicking this while a filter is active triggers the crash
New-UDButton -Text 'Sync (triggers crash if filter active)' -OnClick {
    Sync-UDElement -Id 'dynTable'
}

New-UDDynamic -Id 'dynTable' -Content {

    New-UDTable -Id 'tblRepro' -ShowFilter -ShowSelection -Dense -LoadData {

        $TableData     = ConvertFrom-Json $Body
        $allFilters    = @($TableData.filters)
        $filterCompany = $allFilters | Where-Object { $_.id -eq 'company_name' }
        $filteredData  = @($Cache:BugReproData)

        if ($filterCompany -and ![string]::IsNullOrEmpty($filterCompany.value)) {
            $filteredData = @($filteredData | Where-Object {
                $_.COMPANY_NAME -eq $filterCompany.value
            })
        }

        $filteredData | Out-UDTableData `
            -Page       $TableData.page `
            -TotalCount $filteredData.Count `
            -Properties $TableData.properties

    } -Columns @(

        # ← Change to -FilterType text to confirm the bug is filter-type specific
        New-UDTableColumn -Property 'COMPANY_NAME' -Title 'Company Name' `
            -ShowFilter -FilterType autocomplete

        New-UDTableColumn -Property 'NAME' -Title 'Name'
        New-UDTableColumn -Property 'ID'   -Title 'ID'
    )
}
}

Notes:

Works fine with no filter active when Sync fires
Works fine with -FilterType text
Passing explicit -Options to the column does not help
Both autocomplete and select filter types are affected
Workaround (until fixed):

New-UDTableColumn -Property ‘COMPANY_NAME’ -Title ‘Company Name’ `
-ShowFilter -FilterType text
Has anyone else hit this? Hoping the team can fix the unguarded .forEach() call in filters.js:209.
