SyncFlowInstances with Certificate Authentication

[sairao77]

Hi,I am able to gather info on various flows(power automate) associated with a list when authenticating Interactive, but If I try the same command with a certificate authentication, I am getting an error. Below is sample of my code where I am getting error. Is this a permissions issue?

$ctx = Get-PnPContext $lists = Get-PnPList
$nestedpowerautomatehash = @{}
foreach($list in $lists){
$flowInstances = $list.SyncFlowInstances($null)
$ctx.Load($flowInstances)
Invoke-PnPQuery
