Azure service cme test error "a bytes-like object is required, not 'str'"

[Paul_Manalaysay]

Hello Checkmates community,

I'm trying to configure VMSS autoprov on Azure but when I run "service cme test" I got this error:

Testing cbccgdr...
ERROR: Controller cbccgdr failed
ERROR details: a bytes-like object is required, not 'str'

Hope someone from the community can help.

 R&D are looking into that and will update once the issue is resolved

Normally you get this error if you run "service cme test" without setting up azure AD application and application access to subscription.

Following the admin guide: Don´t run service cme test before you finished Step 5.

In addition, the CME Log should give a good understanding what´s going on in the background.

Review logs are created by the CME on the Management Server:

/var/log/CPcme/cme.log*

look for an authorization failed message like the following: 

cloud_connectors.https.RequestException: HTTP/1.1 403 Forbidden

b'{"error":{"code":"AuthorizationFailed","message":"The client \'xxxxxxxxxxx' with object id \'xxxxxxxxxx' does not have authorization to perform action \'Microsoft.Network/virtualNetworks/read\' over scope \'/subscriptions/xxxxxxxx\' or the scope is invalid. If access was recently granted, please refresh your credentials."}}'

Hi Andre,

That's is correct, I found out that this is a authorization/IAM issue. I added the service principal application as contributor on VNET and VMSS. 

Now it works fine. Thank you!

This error can occurs if you use wrong VMSS object in the Access control (IAM).
