Rsync In one Dataset, possible to store the data in another dataset?

Hi,
pretty new to TrueNAS, still trying to figure out stuff, currently trying to transfer data from Synology to TrueNas as an additional backup.
I have Rsync installed on one dataset, this is where all my app would be installed.
The other dataset is where I want to store all my files. I tried the whole setup with Rysnc just retrieving all data to the same dataset as Rsync and it works well.
Upon changing the Rsync module config to the dataset path I need, The Rsync config breaks. When tried config again Synology I am hit up with an error, screenshot attached.

I am using the same user and credentials, I have tried the giving the destination dataset random permission that I saw the dataset with Rsync installed has.
What might I be Missing?

Any help is great! Thank you!
