BadRequest on TextAnalytics DetectLanguage - InvalidRequestQueryString

[quincyt]

Hi all,

I'm working on a PowerApp in which I'm trying to implement TextAnalytics. To understand how TextAnalytics works, I first followed the blog from @mblythe at https://powerapps.microsoft.com/en-us/blog/custom-connectors-and-text-analytics-in-powerapps-part-on....

From that blog I got the Sentiment and KeyPhrases part working (so my Text Analytics service in Azure works), but the DetectLanguage part keeps returning the following error:

The code I'm using to trigger it is:

ClearCollect( colLanguage, 
    TextAnalytics.DetectLanguage(
        {
            numberOfLanguagesToDetect: 1, 
            text: txtTextToAnalyze.Text
        }
    ).detectedLanguages.name
)

Anybody ran into the same issue and knows how to solve it? According to PowerApps itself the code should be fine as well. Also I can't find other posts on the internet about this specific error message.

Thanks in advance for your effort and response! Cheers, Quincy.

Hi did you find a resolution to this? I've got the same issue

Hi @alopes21,

I'm afraid not. In my case, it was for demo purposes only. For my demo, I just filled the Language info by hand (just to fool the attendees). It's definitely an issue in the TextAnalytics Connector in PowerApps, because the API itself from Azure works fine. If you must fix it for your purpose, you could use Flow to make a direct web service call to the API. Initiate the Flow from PowerApps and send the input text along with it. Then make a web service call to the TextAnalytics API in Azure and use a Respond action in Flow to get the result back in PowerApps in a collection. This is what I used to get almost all other Cognitive Services (the Face and Speech API's were the hardest, but I got it to work) to work in my demo PowerApp.

If you need extra help, let me know. Cheers, Quincy

Hello quincyt,

I just have deleted the part of numberofLanguagesToDetect:1 and then the laungage detection works. But I donnot know why.

Thanks.
