Hello ​@evoteck 

The error appears to originate from a PythonCaller transformer. The error is specifically about a Python library/module named GeoEncoder that the Python script in the transformer named GeoEncoder - API uses.

To resolve a ModuleNotFoundError, you would install the missing library into your machine. However, there does not appear to be a publicly shared library or script named GeoEncoder available online. I suspect this may be a custom library that someone has made.

I would recommend reaching out to the person who created this workspace to see if they are able to share the GeoEncoder library/module with you.

Hello ​@debbiatsafe yes I want to recreate the workflow , since the I do not have access to the GeoEnccoder library, and do creator no longer work with my company, the functionality of the workflow will be to create a unique id for a newly captured Distribution Substation and HT pole from the field which starting from the last one created from the database. So the you have an idea about the best approach to create this.

Assuming you do not want to solve this with Python, I think you could achieve this with a combination of a UUIDGenerator, some Testers, and maybe conditional values in an AttributeManager.
 

You will need to elaborate further on your use case, provide some sample data, your current workspace, and additional screenshots of what your desired outcome should be - before anyone can attempt to help you with this workflow further. 
 

and if you run into any errors or require further troubleshooting in the future, I recommend that you submit a support ticket for us to assist more in depth!
