Migrating code from ArcGIS Desktop python 2.7.3 to ArcGIS Pro python 3.6.2

SyedGardezi

I am calling the following function:

import arcpy

arcpy.JoinField_management(in_data,in_field,join_table,join_table_field,fields)

It works perfectly fine using ArcGIS Desktop python 2.6 but gives the following trace using ArcGIS Pro python arcgispro-py3

input parameters:
  arcpy.JoinField_management(
  temp_layer,
  NEAR_FID,
  xyz.gdb\xyz\xyz,
  OBJECTID,
  dict_values(['xyz']
)

Traceback (most recent call last):
    arcpy.JoinField_management(in_data,in_field,join_table,join_table_field,fields)
    raise e
    retval = convertArcObjectToPythonObject(gp.JoinField_management(*gp_fixargs((in_data, in_field, join_table, join_field, fields), True)))
    return lambda *args: val(*gp_fixargs(args, True))
RuntimeError: Object: Error in executing tool

I check I passed exactly  the same varabiels to both function but I am getting this error. can you give soem hints as to what might be the issue?

• you are missing a ")" at the end of dict_values
• xyz.gdb\xyz\xyz needs to be r"xyz.gdb\xyz\xyz"   if that is the real gdb name
• Analyze Tools For Pro—Data Management toolbox | ArcGIS Desktop 

should be used to check for 2 to 3 changes in tool parameters etc
