Web Chat shows retry but message is really sent to bot

[alokraj68]

Hi,
The web chat is showing could not send please retry, but the message is really sent to bot. what really goes wrong is that user will press retry and the bot will get the message every time the retry is pressed.

I am having the same issue. My bot is doing image analysis so it could take up to 10 seconds to respond.

[alokraj68]

Yeah! And also, if we open the same web chat in 2 tabs lets say the bot is present over a website it will throw 412 precondition failed. Which again breaks the conversation.

Other channels allow 15 seconds to respond. It would be nice if webchat abided this timeout too.

How quickly is "retry" shown? Which SDK are you using?

DirectLineJS (which is what WebChat uses) actually observes a 20 second timeout. If it's showing "retry" before then, it's because of a different problem.

@alokraj68 I don't quite understand your scenario but it sounds like a different bug. Please open a new issue for it.

I am also facing the same issue, the bot responds with "couldn't send retry" but actually the conversation proceeds. How can i fix this?

[ohmusama]

We fixed this by immediately returning from the message controller with HttpOK. And start the bot in a async void background thread.

I would still like to know more about this problem. WebChat/DirectLineJS has a 20 second timeout. Are you all seeing faster fails than that? If so it's (probably) not on the client side. In your response please say which SDK you are using (.net or node).

[ohmusama]

In telemetry we were seeing intermittent 15s timeouts, but it appeared to the client faster on occasion. We assumed it was our fault.

Hi guys,
Am also receiving a similar error in telemetry. am using .net SDK.
This error started to creep in recently. we are not able to identify what causes this error.

[akasranjan005]

I am using rest api on python, maybe the case is of timeout but how can i handle it if the processing work takes more than 20 sec?

[alokraj68]

but in our case, the processing is not taking that long when we do the testing,

I'm having the same issue with the built in iframe.
Facing two errors:

• Couldnt send
• My bot code is having issues

[danmarshall]

Hello everyone, here's a couple of tips for these kinds of errors.

• Make sure you log all errors in your bot. If your bot returns an HTTP 500, Direct Line will then pass that as a 502, which will appear as a failure to Web Chat. You will need to know why your bot had the 500 error.
• If you are using the .NET SDK, and you are logging errors, and your error is "Authorization for Microsoft App ID failed with status code Forbidden", then you may need to add a call to MicrosoftAppCredentials.TrustServiceUrl(serviceUrl) - see BotBuilder solutions for similar issues.
