dropbox_put() issue

Hy friend, i am getting an error when want to upload data.frames or files...i tried with

> dropbox_save(dropbox_credentials,table1, file="public/table.csv")

and it give me a table with "RDX2" and NA values...the other option is with "dropbox_put"

> dropbox_put(dropbox_credentials, what="table.csv", filename="public/table.csv")
> Error in if (size > 1048576 \* 150) return(dropbox_chunked(cred, what, : missing value where TRUE/FALSE needed

but it is a problem, where can I put that the size is no bigger than 1048576 \* 150??

any suggestion ?
