11 Test it in your Dialogflow simulator
Try a query like “what is the color of Mars” inside the Dialogflow simulator. You should see a response similar to the following.
Access the endpoint in your browser, just as you did in step 7. Do you see an error message? If yes, wait for a few minutes and try again.
On the other hand, if you do see a proper output when you access the endpoint in your browser and you see your query fail inside the simulator, there is something else going on. Please copy the error message from inside the DIAGNOSTIC INFO of your Dialogflow simulator and leave a comment with the error message that you see.
