Hey!

I am trying to use the module @hermannp/node-red-getproduction-fusionsolar ([node-red-getproduction-fusionsolar (node) - Node-RED](https://flows.nodered.org/node/@hermannp/node-red-getproduction-fusionsolar/in/udGkcCy3MDwK))

Unfortunately, it returns "Error: Invalid credentials for openAPI login"

I verified that the credentials are correct via Postman. The problem is that the code of the module expects a field in the returned object to fetch a token, but the token is in fact returned in a cookie (see instructions here: [Communicate with FusionSolar through an openAPI Account - Huawei Enterprise Support Community](https://forum.huawei.com/enterprise/en/communicate-with-fusionsolar-through-an-openapi-account/thread/591478-100027))

I was looking for reaching out to the author directly here or on NPM, but I seem to be blind 🙂

Any help is appreciated.

Thanks,  
TBO
