Power Automate INVALID PARAMETER - Generate Document from MSFT data and word template

I am trying to generate a PDF document from a Microsoft forms. 

The problems is that I keep having an INVALID PARAMETER because one of the data in the form. 

The data is generated from a question in which the person can choose more than one option (check boxes). In excel the data appears like this: ["Docking Station","Monitor"] and when I try to merge files the system gets in conflict and generates the below JSON: 

{
"Equipamentos": "["Docking Station","Monitor"]"
}

With that above JSON it is not possible finalize the flow..

Grateful if anyone could help me with this issue.
