Microsoft Graph API insert new ListItem Field Datetime gap to 8 hours

When we try to insert a new item with a DateTime field in a List of Sharepoint through Microsoft Graph Api V1.0 or Beta version. The API return us it new item with 8 hours of gap.

We are using Microsoft-sdk-javascript, but i think that this is not the problem. When we update any item, we don't have this issue.

For insert the DateTime we use ISOString according to documentation.

 var data = { fields: {
                            Title: 'test',
                            Fecha: moment().utc().toISOString(),
                        }
                    }
                    var result = await graph.insertItemListBeta(accessToken, listTestId, data);

We return this gap of hours (8 hours)

Do you have a solution for this??

Thanks you in advanced.

We try this in Postman and we have the same result.
