Help with Connect-PnPOnline Error The input is not a valid Base-64 string

[myatix]

Hi All,

I am having an issue connecting to using Connect-PnPOnline

$tenant = $env:Tenant
$clientId = $env:ClientId
$certificateBase64Encoded = $env:Certificate
$templateLibUrl = $env:TemplateLibUrl

Connect-PnPOnline -Url $templateSiteUrl -Tenant $tenant -ClientId $clientId -CertificateBase64Encoded $certificateBase64Encoded

[Error] ERROR: The input is not a valid Base-64 string as it contains a non-base 64 character, more than two padding characters, or an illegal character among the padding characters.

My Certificate is stored in an Azure Key Vault and the $env:Certificate points to the Key Vault Certificate Identifier.

Can someone tell me why it returns this error?

It sounds like your base64 encoded cert isnt stored correctly in KV.

If you have access to KV you could verify the string. It should be a very long string that contain no whitespaces.
Usually it starts with something like MIIKcQIBAzCCCi0GCSqGSIb3DQEHA (example) and ends with =

@AndersRask Thanks for the response!

The certificate Identifier is https:/kv-xxxxx.vault.azure.net/certificates//GUID

My Mistake...

This resolved the issue... :)

@Microsoft.KeyVault(SecretUri=https:/kv-xxxxx.vault.azure.net/certificates/GUID)
