Scanning user input and looking for keywords

Original post:

I am trying to load a json file as a javascript object. I then convert the keys into their own array. I am then trying to search through a user input string to find any matches. If a match is found I then want it to then check if the value of that key is "next" and if so do one thing. If the value is not "next" I want it to do a different thing. If none of the keys match any of the words in the user input string I want it to send an error message. This last part seems to be the issue. When a user types a string without a keyword it will sometimes log the error message more than once. I have noticed that this happens especially when a new json file is loaded. Here is a link to where I think the issue is. I have tried just about everything I can think of but every solution seems to have the same problem so maybe I am just looking in the wrong place. If you have any questions or need more information please let me know.

Edit:

I have an object that looks like this:

var object = {"keyword": "next", "other word": "wrong", "test": "wrong"}

it was loaded from a json file accessed from the server using the fetch API. I then have an input box that when a user enters one of the three keys of the object should echo its value on enter. If no keys are found in the string the user has input it should print out an error message. If the value of the key is "next" it should run a function called loadlevel() to load the next level. That next level is then loaded in the same way as the aforementioned one. This appears to be where I am having issues. When it loads the new json file it seems that both the previous object and the new object are still running. This causes it to print out the error message if the new input doesn't match both the new keys. See example below:

Setup:

//This is the first object loaded from the json file:
var object = {"keyword": "next", "other word": "wrong", "test": "wrong"}

What Should happen

When the user inputs the following strings it should have the corresponding outputs:

"this is the other word" => "wrong"
"hello, world" => "error"
"this is the keyword" => "next" loadlevel()

When the next level is loaded, say this for example:

var object = {"smith": "next", "hello": "wrong", "hi there": "wrong"}

It should then output this:

"this is the other word" => "error"
"hello, world" => "wrong"
"this is smith" => "next" loadlevel()

What is happening

The first values seem to work fine:

"this is the other word" => "wrong"
"hello, world" => "error"
"this is the keyword" => "next" loadlevel()
