Hi Schindar! I'm happy to help.

The image caption sample depends on some environment variables stored in the ".env" file. If you just copied and pasted the JavaScript code then you may be missing some of the extra files you need. It's a good idea to clone the whole repository to make sure you're not missing anything.

If you look inside caption-service.js, you can see the line var apiUrl = process.env.MICROSOFT_VISION_API_ENDPOINT + '/analyze?visualFeatures=Description' in two places. What's happening here is that it's trying to get a URL from the environment variable MICROSOFT_VISION_API_ENDPOINT but the variable is undefined in your case. If you have the correct .env file, the variable should be defined as https://westus.api.cognitive.microsoft.com/vision/v1.0.

Hey Schindar. Did you clone the repository?

Go ahead and have a look at the files for the image caption sample: https://github.com/Microsoft/BotBuilder-Samples/tree/master/Node/intelligence-ImageCaption

Among those files you will see a file called .env: https://github.com/Microsoft/BotBuilder-Samples/blob/master/Node/intelligence-ImageCaption/.env

The contents of that file look like this:

# Bot Framework Variables
MICROSOFT_APP_ID=
MICROSOFT_APP_PASSWORD=

# Subscribe to Cognitive Services Computer Vision API to obtain a Trial Key.
# Subscription URL: https://www.microsoft.com/cognitive-services/en-us/subscriptions
MICROSOFT_VISION_API_KEY=
MICROSOFT_VISION_API_ENDPOINT=https://westus.api.cognitive.microsoft.com/vision/v1.0

As you can see, you are not supposed to "click on the link" but rather use the URL https://westus.api.cognitive.microsoft.com/vision/v1.0 as the value for the environment variable MICROSOFT_VISION_API_ENDPOINT.

Also note that you will need a value for MICROSOFT_VISION_API_KEY. As the comments say, you can get help obtaining a key from the link https://www.microsoft.com/cognitive-services/en-us/subscriptions. Yes, you are supposed to click that one. ;)

There are many sources where you can read more about NodeJS environment variables, such as: https://codeburst.io/process-env-what-it-is-and-why-when-how-to-use-it-effectively-505d0b2831e7 https://www.twilio.com/blog/2017/08/working-with-environment-variables-in-node-js.html https://nodejs.org/api/process.html

Can you post a screenshot of your bot's folder in File Explorer?

[v-kydela]

Also, did you clone the repository or not?

Please compare the code you copied with the code in the repo's app.js. Note that this line loads the environment variables from the .env file: require('dotenv-extended').load();
