Error: Ghidra throws error while loading simple STM32F446 cmsis file

[autohacx]

I was trying to run SVD_Loader.py and import and cmsis file for cortex arm little endian processor.
However, Ghidra throws me an error -

Traceback (most recent call last):
line 149, in
t = currentProgram.memory.createUninitializedBlock(r.name, addr, length, False)
AttributeError: 'ProgramDB' object has no attribute 'memory'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "/Users/x/Extensions/Ghidrathon/data/python/jeprunscript.py", line 31, in jep_runscript
exec(compile(source, path, "exec"), {**globals(), **additional_globals})
File "/Users/x/mystuff/ghidra_10.3.2_PUBLIC/ossplugins/test.py", line 155, in
except ghidra.program.model.mem.MemoryConflictException as e:
NameError: name 'ghidra' is not defined

I am unsure about what to do and where to make any changes to fix this for loading the correct memory map for my controller for reversing.
