[Bug] Import JSON config with DuckDB doesn't work properly

[mytototo]

Describe the bug

Importing a JSON config in the DuckDB demo can fail on 2 scenarios from what I've tested so far.

To Reproduce
Steps to reproduce the behavior:

1. Add at least one dataset to kepler.gl, which includes a timestamp.
2. Add a filter on the timestamp to have a timeline.
3. Export the map as a JSON config.
4. When importing the map from the save JSON config, it fails.
   1. The first error is not related to the timestamp filter and happens no matter what:

   Error: IO Error: GDAL Error (4): `-w9n0uh' not recognized as a supported file format.
   

   2. After removing the prefix - to only keep w9n0uh everywhere in the JSON config, the import works if no timestamp filter was present. However, if a timestamp was present while exporting the JSON config, the following error is encountered:

   Error: IO Error: GDAL Error (4): `w9n0uh' not recognized as a supported file format.
   

Expected behavior
Importing a map should work and should also include the timestamp filter.
