I have faced that issue some time ago.
I searched the community and google.But I found only that firebase is not sending complete sentence.
So you can do two things-
1.When you store data from kodular app then replace all spaces by a number or symbol.
And when you got value then replace that number or symbol by spaces.
2.You can leave firebase and make your own storage with TinyWebDB. Hosting your own TinyWebDB
OR
You can switch to airtable or mysql.
