Einstein Analytics REST API query

Hi
I'm using this code to connect to Einstein Analytics in Salesforce and fetch data using Rest APIs
let
    token_url = "https://login.salesforce.com/services/oauth2/token",   
    api_base_url = "https://***.my.salesforce.com/services/data/v48.0/wave/query",
    qry_str = "",
   body="grant_type=password&client_id=***&client_secret=***&username=***&password=***",
   Source  = Json.Document(Web.Contents(token_url,
   [
     Headers = [#"Content-Type"="application/x-www-form-urlencoded"],
     Content=Text.ToBinary(body)
   ]
   )
   ),
    token = Source[access_token],
content = "{
    ""query"":""q = load \""DataSetName\"";  
     q = limit q 200;""
}",
    data= Json.Document(Web.Contents(api_base_url&qry_str,
   [
     Headers = [
                #"Authorization"="Bearer "&token,#"Content-Type"="application/json"],Content=Text.ToBinary(content)
    
   ]
   )
   )
in
    data
 
 
 
the Authentication works fine and I can get the access token and connect but when I post the second request I get this error: "We couldn't authenticate with the credentials provided"
Am I sending the post request correctly by using Content=Text.ToBinary(content)? or maybe my SAQL query is wrong? as I'm not familiar with SAQL.
the below code works:
  
    api_base_url = "https://***.my.salesforce.com/services/data/v42.0/wave",
  
    data= Json.Document(Web.Contents(api_base_url&qry_str,
   [
     Headers = [
                #"Authorization"="Bearer "&token,#"Content-Type"="application/json"]
    
   ]
   )
   )
  
but when I change the URL to   "https://***.my.salesforce.com/services/data/v48.0/wave/query" and post the query it breaks.
Any help with this will be greatly appreciated.
Thanks
Zara

Hi Guys 

 

In case anybody else faces this issue, I solved it by adding \n to my query:

 

content = "{
    ""query"":""q = load \""DataSetName\"";  \n q = limit q 200;""
}",
