Undefined error when parsing QnA file using LU parser

[chrimc62]

Versions

@microsoft/botframework-cli/4.15.0-dev.20210723.bf1f054 win32-x64 node-v14.16.0

Describe the bug

This was reported by a customer. If you have a QnA file with a link across multiple lines then you will get an 'undefined' error rather than any useful diagnostics.

To Reproduce

1. Create a QnA File foo.qna like:

**Prompts:**
- [Files that Cannot Sync
](#1)

<a id = "1"/>

## ? Files that Cannot Sync
```
Files that cannot sync.
```

2. bf orchestrator:create -i foo.qna -m basemodel
3. You will get an undefined error in BuildDialognostic because context is a string and not a structure.

    else if (context !== undefined) {
        const startPosition = new Position(context.start.line, context.start.column);

Expected behavior

An error message indicating the line.

I have the same problem here. I'm working with tsv files meanwhile

@jongon, could you share the problematic .qna file?

[tsuwandy]

Looks like the content in the example above is invalid, see this page for valid .qna content. https://docs.microsoft.com/en-us/azure/bot-service/file-format/bot-builder-qna-file-format?view=azure-bot-service-4.0

Prompts should be part of a question. The following works fine:

# ?store hours
```
Most our stores are open M-F 9AM-10PM.
```
**Prompts:**
- [Files that Cannot Sync](#1)

<a id = "1"></a>

# ? Files that Cannot Sync
```
Files that cannot sync.
```

Fix should be available with the next bf cli daily deployment.

Hi @tsuwandy, what do you mean by the daily deployment?
I'm facing the exact same issue using the latest release.

[tsuwandy]

@fedsp, did you try this:
npm i -g @microsoft/botframework-cli@4.15.0-dev.20211004.edcf63e

Great! Upgrading to this specific version did the trick.

In the future it will be integrated in the main stable version, right?
