ArcGIS Pro Python script troubleshooting

II need help troubleshooting a specific issue with a Python script used in ArcGIS Pro. I'm working on configuring the BRAT python toolbox from Riverscapes (https://brat.riverscapes.net) to run on a specific area. I am running into an error message when running one part of the tool. I'm a GIS analyst with some Python experience looking for the help of a Python programmer with some ArcGIS experience. The error may be a quick one to resolve, but I'm a bit stuck and would like to hire someone for some guidance. I've managed to set up the toolbox and run parts of the code thus far, but have run into the following error while running a script that references some modules:


File "C:\...\BRAT\SourceCode\SupportingFunctions.py", line 111, in make_layer
# arcpy.MakeFeatureLayer_management(layer_base, new_layer)

AttributeError: module 'arcpy' has no attribute 'MakeFeatureLayer'


Let me know if you think you may be able to help and I can send over the scripts for your review. Thank you!
