Power Automate how to use action parameters with @ in name

[Christoph]

Hey Community,

At the moment I try to implement a Flow, which should trigger the Dataverse Function "CalculateRollupField" via a custom connector. (see blog article: https://www.powerappsguy.com/blog/Use-Power-Automate-Flows-to-Calculate-Rollup-Fields/).

API Call: https://[YOUR_ORG].crm4.dynamics.com/api/data/v9.1/CalculateRollupField(Target=@target,FieldName=@fieldname)?@target={'@odata.id':'[your_entity]([your_recordid])'}&@fieldname='[your_fieldname]' 

When I try to use the custom connector in Flow I retrieve the following error:

Request to XRM API failed with error: 'Message: Flow client error returned with status code "BadRequest" and details "{"error":{"code":"TemplateValidationError","message":"Die Flowvorlage für die Logik-App des Flows war ungültig. Unable to parse template language expression 'target': expected token 'LeftParenthesis' and actual 'EndOfData'."}}". Code: 0x80060467 InnerError: '.

For me it seems the "@" in the action parameter names is the reason for the error, because its a reserved in the flow expression syntax.

Is there any way to use Actions with such a naming, because Dataverse web api requires such a query string pattern?
