Rest api call giving error for creating a model using the mtypeid parameter in Spectrum

Products

• CA Spectrum
• DX NetOps

Issue/Introduction

We have a script which does the onboarding of the devices (SNMP/pingable) in the spectrum via rest API calls.

After the upgrade to 21.2.8 we see the issue in the inserting of the devices (discovery of the devices) via rest api call

We can delete the device without an issue in the same script but insertion is giving us an error.

Error:
