I ran into this exact issue when trying to use the Agent.Name demand in the API call to force a specific agent to run a pipeline. The syntax that actually worked was quite different from the documented one:

For your example this should do the trick
{"definition":{"id":"539"},"sourceBranch":"dev","demands":[{"value":"Massrun -equals True"}]}
This worked in on-prem Azure Devops Server 2020
