Direct Line Speech throw "actions of null" error when bot is on unsupported region

I was using this example to implement directline speech in webchat. Here is the script I used

<div id="webchat"></div>
    <script>
        (async function () {
            const store = window.WebChat.createStore({}, ({ dispatch }) => next => action => {
                if (action.type === 'DIRECT_LINE/CONNECT_FULFILLED') {
                    dispatch({
                        type: 'WEB_CHAT/SEND_EVENT',
                        payload: {
                            name: 'webchat/join',
                            value: 'name'
                        }
                    });
                }
                return next(action);
            });

            const adapters = await window.WebChat.createDirectLineSpeechAdapters({
                fetchCredentials: {
                    region: 'region',
                    subscriptionKey: 'key'
                }
            });


            window.WebChat.renderWebChat(
                {

                    ...adapters, store
                },
                document.getElementById('webchat')
            );

            document.querySelector('#webchat > *').focus();
        })().catch(err => console.error(err));
    </script>

seems like “…adapters” is not supported in Edge or IE, How can I change it so that it will be working in Edge and IE ?

Hi, today we have same problem with westeurope region but we are unable to change the region of service. We use the npm package. Until saturday I’m sure that it works, any help?

Thanks

I’m also facing this issue again, I have raised a support request from Azure. Will keep you updated, if i get to resolve this.

Hi, For me this issue was resolved without making any changes in code or configuration. I believe this issue was from the speech API side. It got resolved 3 to 4 days after reporting and it never occurred again.
