Web.contents unbale to authenticate with anonymous authentication

Hey folks, I hope I can get some help with an issue I am facing.

I am retrieving data from an API that uses JWT token for authentication. So I have to make 2 requests:

1. To login and get the token.

//Get JSON Web Token via API
optionsToken = [#"Content-Type"="application/json; charset=UTF-8"],
bodyToken = "{""username"":""real_username"",""password"":""real_password""}", 
responseToken = Web.Contents(urlApi & pathToken,[Headers = optionsToken,Content = Text.ToBinary(bodyToken)]),

//Get Access Token and Token Type
responseJson = Json.Document(responseToken),
// name of the token property
accessToken = responseJson[token]

2. Make the data request with the token

//Get Data
optionsData = [#"Content-Type"="application/json; charset=UTF-8",#"x-redlock-auth"=accessToken],
postData = "{""sample_post_data""}",

responseData = Web.Contents(
	urlApi & pathData,
	[
		Headers = optionsData,
		Content = Text.ToBinary(postData)
	]
),
data = Json.Document(responseData)

The API requires using POST method so I need to use Anonymous authentication and format the headers and body properly with using the `Content` option.

All of that is working fine and I am able to get the data with the data call. But when I attempt to perform any transformations on the data I get the error "We couldn't authenticate with the credentials provided.

If I go into advanced editor and copy the code with the new transform step and use it in a newly openned document it works. This is the case for any subsequent step I attempt on the data.
