R help - Jul 2020 - aws.s3::s3sync Error in curl::curl_fetch_disk(url, x$path, handle = handle) : Failed to open file

I am trying to use aws.s3::s3sync to sync the contents of a bucket to an
aws ec2 instance ( via rstudio server)

my script is as follows I cannot make a repro since that would need to be
run from the instance with my account key and details ( replaced with
xxxxxxxxxxxxxx below).

all files I am trying to sync are under the s3 prefix  FAME_FMR which is
the only top level "directory" in the bucket
Have I missed a setting?
If not any suggestions on this error?

thanks
