I have added the correct domian name i get an error of Access-Control-Allow-Methods kindly help me
TL;DR
Developers are encountering an error related to Access-Control-Allow-Methods despite adding the correct domain name. Double-check variable usage and permissions, and ensure the database and project settings are correct. Review the code for any mistakes. 
What's your code?
Are you sure that the database and project is correctly set?
Double check that where you're using it is correct
do u want to know more about this error ???
or anything specific ?
And actually this document is in relation with different document with in the same collection
I saw the screenshot. Deleting as you have permissions set to any
I mean, where you're using the variable, double check you're not misspelling it
