AppwriteException: Document with the requested ID already exists.

I am using appwrite in react js. I have Array of data. I am trying to create new document in database. For that I am looping through array of data and creating new document. The first document is successfully created but for the next document i get "Document with the requested ID already exists" error. I am not sure why this issue. I am providing unique iD. I tried with storage and it works perfectly. I am using appwrite version 1.3.8

Not sure if this is anything but your database variable is database not databases.

Do you have a unique index on the collection?

my bad, in real code the variable name is right . i was trying to summarize my code to put it here, that time i made typo.

yes i have

It says failed but maybe it sure create... So you can get that error because of the unique index too

I removed all indexes and I still get this error. however i created new collection with only two attribute(with unique index) and it is working. in my old collection i do have data which i manually inserted using appwrited dashboard and later i tried to upload using appwrite api. for now i will try few other things.

Maybe one of the existing documents caused the conflict
