Runtime error reading bp files

Hi! I have been using openpmd-api for a while and I did not have any issues reading .bp files with openPMD-api in Python. Recently I am facing an issue with reading bp files. When I execute:

```py
series_4h = io.Series("/gpfs/aps/simulations/planewave_08/output-0000/planewave_08/planewave_08.it00000%T.bp"
,io.Access.read_only)
```

I get the following error:

```RuntimeError: [setAttribute] Value for string attribute 'patchSuffixes' must not be empty!```

I am using openpmd-api 0.14.4 and I have attached the bp file.
