In payload invalid data source [CredentiallessDiscovery] exist. You need to provide a valid choice value from field [discovery_source] in table [cmdb_ci]

Discovery error: 

In payload invalid data source [CredentiallessDiscovery] exist. You need to provide a valid choice value from field [discovery_source] in table [cmdb_ci]

The error wil often be seen when:

• Credentialless discovery is enabled.
• A discovery pattern is triggered which updates discovery_source field to CredentiallessDiscovery

The CredentiallessDiscovery choice is not present on sys_choice table for Discovery Source column and table cmdb_ci.

Note: This same error can happen for other discovery sources as well. The resolution would be the same as listed in the following "Resolution" section.

Note: Please test resolutions on a non-production instance first.

Manually create the record or import attached sys_choice record.
