The problem is double.

The export function don't export the adapter (a function) --> first problem The missing value is config -> annotation -> adapter. So when the retrieve annotation function try to use the adapter, a TypeError error is thrown

The import don't check if the value is set --> second problem In retrieve function in externalStorageAnnotationplugin, I add the following checks. It can be improved

if (typeof config.annotation.adapter === 'string' && config.annotation.adapter === AnnotationAdapter.LOCAL_STORAGE) {
  config.annotation.adapter = (canvasId) => new LocalStorageAdapter(`localStorage://?canvasId=${canvasId}`);
}
if(typeof config.annotation.adapter === 'string' && config.annotation.adapter  === AnnotationAdapter.ANNOTOT) {
  const endpointUrl = 'http://127.0.0.1:3000/annotations';
  config.annotation.adapter = (canvasId) => new AnnototAdapter(canvasId, endpointUrl);
}
if (!config.annotation.adapter) {
  // Default adapter set to LocalStorageAdapter
  config.annotation.adapter = (canvasId) => new LocalStorageAdapter(`localStorage://?canvasId=${canvasId}`);
}
