Dynamic DataSource - Cannot find issue with code

Trying to get this datasource to refresh online, but am getting the dynamic datasource issue.

I've replaced the dynamic elements in the Web.Contents queries using relativepath, but am still getting the error. Any Ideas?

let
    
    // API Credentials
    oauthSite = "https://<REDACTED>.docebosaas.com",
    oauthEndpoint = "/oauth2/token",
    clientId = "<REDACTED>",
    clientSecret = "<REDACTED>",

    // User Credentials
    email = "<REDACTED>",
    pwd = "<REDACTED>",

    // Assemble Token URL
    tokenURL = "client_id=" & clientId & "&" & "client_secret=" & clientSecret & "&" & "grant_type=password&scope=api&username=" & email & "&" & "password=" & pwd,
    binaryTokenURL = Text.ToBinary(tokenURL),
    
    // Call for Token
    tokenData = Json.Document(Web.Contents("https://<REDACTED>.docebosaas.com/oauth2/token", [Headers = [#"Content-Type"="application/x-www-form-urlencoded"], Content=binaryTokenURL])),
    
    // Extract the token from the returned table
