ERROR: "MicrosoftTranslator.Translate failed: The Method 'Translate' has an invalid value for parameter 'languageTo'"

[tperry]

This error pops up for ~20 seconds when I first open the application I have created through the Powerapps app on my mobile.
"MicrosoftTranslator.Translate failed: The Method 'Translate' has an invalid value for parameter 'languageTo'"

The error only shows right when the app is opened. I do not have any issues with anything being translated, and there are no issues when in Dev mode. There is no error in the App Checker. 

I have a combobox where the default value is English but the user can choose any of the languages provides though the MicrosoftTranslate connector. My formula on the items being translated is:

If(
lang.Code = "en",
[Translate Text Goes Here],
MicrosoftTranslator.Translate(
[Translate Text Goes Here],
lang.Code
)
)

I am not sure why this error is showing when nothing seems to be wrong.

It seems to be related to this issue which never received a solution.

Hi @tperry 

What do you have on the "OnStart" property for your app? Is there any situation, where a call is made to the Translator when the app is opened? 

Hope this Helps!

Hi yashag2255!

I do not have anything in the OnStart, but I do have an OnVisible on the home page, that sets "English" as the default via a global variable. 

I tried moving that to the OnStart section and it has not changed anything. 

Example:
OnStart = Set(GV_Language, "English")

I guess I am not sure what kind of call needs to be made to the translator to initialize it?

Hi @tperry ,

Could you show me your formula about MicrosoftTranslator.Translate?

I've made a similar test , use "English" in this function will not work.

Please try this:

MicrosoftTranslator.Translate(text that you want to translate,"en")

Here's a doc about this connector for your reference:

Best regards,

It's a conditional value based on the language the user is selecting in the dropdown. 

If(dd_languages.Selected.Code="en","Text I want to translate",MicrosoftTranslator.Translate("Text I want to translate",dd_languages.Selected.Code))

Set the Combobox default (DefaultSelectedItems) to:

Filter(
    allLanguages,
    Name = "English"
)
