Mulesoft - Patch files by file id connector

Hi

I retrieve a csv file from Google Drive then i insert into a salesforce object. After that process finishes i want to just rename the file using patch files by file id connector:

File Id: vars."gcp.fileId"

Upload type: metadata

Body: 

{

    "name": vars."gcp.newFilename"

}

But I keep getting GOOGLE DRIVE BAD REQUEST error. 

I also tried after the salesforce call to read the file again then delete it then create multipart file with same content but a new file name and i faced an error saying UNABLE_TO_LOCK_ROW.

Please someone advise if you have a solution for this.

Thank you
