I have a issue Cannot convert undefined or null to object TypeError: Cannot convert undefined or null to object at Function.keys () at generateGridColumns (http://localhost:3000/main.e952596e505304fc7155.hot-update.js:41:30)

from meteor.

Hello,
Please tell us more. What you send us doesn't help us in any way, not to mention the way you formatted the issue makes it look like spam.
Here is how things should look and what we need to be able to proceed in helping you:

Title should be short description of the error, not the entire message, that is what description is for. So in this case it should be something like this: generateGridColumns throws undefined
Description should include:
The version of Meteor you are using, what is your front-end (in this case it looks relevant)? What is the error message, what did you do to get the error? What did you do to debug this to identify that it is a Meteor problem? Do you have somewhere minimal replication so that we can go debug the issue straight away?

From the name of the function that generates the error it looks like that function from the front-end library managed to crash the Meteor's hot-update script. Please check the code you have been editing for any undefined input and make allowance for it.

@StorytellerCZ Sorry, you are right. I am correcting by fixing a component of React.js and TSX. It is a custom hook and receives props. I do a search with data that I put in the form and based on the data I put in a comparison is done between all the data in the fetch and if it finds a match it has to populate my table with the results of the search. Hope I explained myself well. If you want I share you the code where I have the problem with code sandbox maybe it is more clear what I am talking about
