Graph token not saving in variable

Question

I'm developing a Power Automate triggered from a SharePoint list to utilize the Graph API to create a Team. I successfully get the token with the HTTP step and parse it with the Parse JSON step, but when I use the Parse JSON output as the input for the Set variable step, it continues to be null. Anyone else coming across this? I've tried in 2 separate tenants and keep getting the same thing.

Hi @Raul Rubalcada

Thank you for posting your question in the Microsoft Q&A forum.

The field you’re referencing (access_token) is not located where Power Automate expects it, and therefore resolves to null when used in Set variable.

Your Parse JSON schema should look like this:

{
    "type": "object",
    "properties": {
        "token_type": {
            "type": "string"
        },
        "expires_in": {
            "type": "integer"
        },
        "ext_expires_in": {
            "type": "integer"
        },
        "access_token": {
            "type": "string"
        }
    }
}

And the flow is like this:

Now the call returns the correct access_token.

I hope this helps.
