Power Automate how to use action parameters with @ in name

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 fĂĽr die Logik-App des Flows war ungĂĽltig. 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?

    The API call works for me. Just make sure that you omit the brackets.

    Correct: accounts(00000000-0000-0000-0000-000000000000)

    Incorrect: [accounts]([00000000-0000-0000-0000-000000000000])
