## Documentation

**Browser** : Firefox 70.0.1  
I just started playing with the Dgraph guided tour in Firefox and when I got to the “Load Data” step and click Run it gave the following error. (NOTE: it only errors in firefox it seems??)

```auto
{"errors":[{"message":"startTs parameter is mandatory while trying to commit","extensions":{"code":"ErrorInvalidRequest"}}]

```

I pulled the latest docker image and I am running in a docker container on windows (linux container hosting)

```auto
docker image inspect dgraph/dgraph
[
    {
        "Id": "sha256:a42a8990ff02df664460fafd62e32fd4800ff03ab388a226fdb2ee27146740ca",
        "RepoTags": [
            "dgraph/dgraph:latest"
        ],
        "RepoDigests": [
            "dgraph/dgraph@sha256:d7dc44603826e5f79bbb165c85c016de3b60acc6bf4fbbc778330a589c7babae"
        ],
...

```

I’m seeing this as well. Looking at the network trace, while the window says that it’s using `/mutate`, it’s actually running `/commit`.

This may be related to [https://github.com/dgraph-io/tutorial/issues/86](https://github.com/dgraph-io/tutorial/issues/86) though it doesn’t seem like it’s fixed, even when using `v1.1.0` as indicated in that issue. I’m using Firefox.

Ping @ashish-goswami || @prashant-shahi || @paulftw

Can you guys check this? This seems to be the old issue with Firefox.
