create_nexus_map(f, default_entry_only=True) infinite loop

[DanPorter]

The following code does not complete:

# Look at Processed file
proc_filespec = "/dls/i10-1/data/2025/nt42193-1/processed/i10-1-%d_xas_notebook.nxs"
import hdfmap 
m = hdfmap.create_nexus_map(proc_filespec % 37436, default_entry_only=True)

Killing it gives the error:

Cell In[36], line 4
      2 proc_filespec = "/dls/i10-1/data/2025/nt42193-1/processed/i10-1-%d_xas_notebook.nxs"
      3 import hdfmap 
----> 4 m = hdfmap.create_nexus_map(proc_filespec % 37436, default_entry_only=True)
      5 #print(m)
      6 #print(m.scannables)
      7 print(m.filename)
