getting Metadata from HGD file set

Hello
I can’t get the get_meta method of the GXHGD class to work.
This is what I type
-->TypeError: get_meta() missing 1 required positional argument: 'meta'
Somehow the method expects a meta object; but this is a get method, not a set method.
I tried passing it an empty meta object, but to no avail:
The GXMETA class description has 3 arguments for all get_* methods; the last of which being the "value to set".
Can anyone help me understand (via a simple example) how the GX methods use get to apparently "set" values ?
Thanks
Mathieu
I can’t get the get_meta method of the GXHGD class to work.
This is what I type
import geosoft.gxapi as gxapi
h1=gxapi.GXHGD.create(“magres_final_gaspe_1998_z19_313.hgd”)
m=h1.get_meta()-->TypeError: get_meta() missing 1 required positional argument: 'meta'
Somehow the method expects a meta object; but this is a get method, not a set method.
I tried passing it an empty meta object, but to no avail:
meta=gxapi.GXMETA()
m=h1.get_meta(meta)
But then I get this message:
File "C:\Users\...\AppData\Local\Programs\Python\Python39\lib\site-packages\geosoft\gxapi\GXHGD.py", line 105, in get_meta
