API to change the name of a dataflow

[Cha74910]

Hello,
I would like to be able to change the name of a dataflow using this API: https://learn.microsoft.com/en-us/rest/api/power-bi/dataflows/update-dataflow

Here is my code:

$body=@{
            name = "DTF TEST Pipeline 1.0.1"
        }

Invoke-PowerBIRestMethod -Url "https://api.powerbi.com/v1.0/myorg/groups/8569358a-549c-466a-894c-de113f5c4fb1/dataflows/8774dad3-3f17-4444-b73b-b82cea0812b6" -Method Patch -Body $body

However when I run the command I get this error message:

Invoke-PowerBIRestMethod : Une ou plusieurs erreurs se sont produites.
Au caractère Ligne:12 : 1

    }
  ]
}

Hello @Cha74910,

It looks like that error that you are receiving is related to the Body parameter.

Body parameter of Invoke-PowerBIRestMethod is Type of String and you are passing a HashTable into it.

Try something like this:

Invoke-PowerBIRestMethod -Url "https://api.powerbi.com/v1.0/myorg/groups/8569358a-549c-466a-894c-de113f5c4fb1/dataflows/8774dad3-3f17-4444-b73b-b82cea0812b6" -Method Patch -Body $($body | ConvertTo-Json)

Hope that helps.
