After truncation, VLStringAtom vlarray write error occurred.

[One-sixth]

The version I tested is v3.9.2 .

import tables as T

db = T.open_file('t1.h5', mode='a')

if 'sad' in db.root:
    db.remove_node('/', 'sad')

arr = db.create_vlarray('/', 'sad', T.VLStringAtom(), chunkshape=[4,])

arr.append('sad')
arr.append('asdsad')
arr.append('asdsadasdsad')

print(arr[:])
arr.truncate(0)

arr.append('sad')
arr.append('asdsad')
arr.append('asdsadasdsad')
print(arr[:])
# bad out

The cmd out

[b'sad', b'asdsad', b'asdsadasdsad']
[b'', b'', b'']
