Rasa lookup table throws error in training data

I followed the blog article Entity extraction with the new lookup table feature in Rasa NLU | The Rasa Blog | Rasa and used a lookup table to recognize location entities in my training data by creating a lookup ‘.txt’ file under the data folder .

I have attached training data ‘data.json’ file . data.json (6.5 KB)

My lookup table file for locations : location.txt (40 Bytes)

When I run ’ rasa train nlu ’ , I’m getting the following error : "Path ‘data’ doesn’t contain valid NLU data in it. Please verify the data format. The NLU model training will be skipped now." What could be the reason ? I only did what was told in the blog. Please tell me where I’m going wrong . Thanks in advance
