SDR Error

Hi,
I tried to run the SDR model but it gave an ERROR such as;
ERROR 1: No PROJ.4 translation for source SRS, coordinate transformation initialization has failed

I am a new user of InVEST model and unable to solve this error, please guide me how to solve this issue.
Thank you and regards,

Please post the log file that the model creates when you run it. It will be in the Workspace you specified, and is called something like InVEST-Sediment-Delivery-Ratio-Model-(SDR)-log-2018-03-03--16_02_58.txt. The log file contains a lot of additional information that might help us see what the problem is. Thanks.
