PowerApps and and AI Builder cloudmersive NLP part of speech tagger


May I please get a quick help in using the AI Cloudmersive NLP connector in PowerApps? My main task is to take an input sentence from the user and preform part of speech tagging using the cloudmersive connector to get the results as nouns, verbs, adverbs ...etc. I have connected the connector to my app and have created a key in cloudmersive. the issue is that the return result in JSON is giving me NULL. NOTE: I do not to use flows or anything I simply want to perform the AI part of speech tagging and display the results in the app in a label (it is fine to have it displayed in JSON format, I want to avoid using flows). My question is what could be the reson for the NULL results? I am using the following formula on a button OnSelect property (I provided a simple sentence as the input for testing purposes: Sara likes apples). here is the command:

 Set( sentenceJSON, JSON(CloudmersiveNLP.PosTaggerTagNouns({InputText:"sara likes apples"}), JSONFormat.IndentFour ))


and the result that I am getting from sentenceJSON lable is:


{ "TaggedSentences": [ { "Words": [ { "Tag": null, "Word": null }, { "Tag": null, "Word": null } ] } ]}

Although the calls on cloudmersive page show that they are successful and the call count is increasing. is there any way to fix this since I want to take the input from the user? I don't want to use databases or flows. Thank you.
