SOLID POD: Error when reading large file with a single chunk

[cdawei]

If there is only a single chunk stored in a large file, loading it throws an error:

type 'String' is not a subtype of type 'Iterable<dynamic>'
#0      fetch (package:solidpod/src/solid/utils/large_file_helper.dart:448:30)
<asynchronous suspension>
#1      readLargeFileAsBytes (package:solidpod/src/solid/utils/large_file_helper.dart:97:3)
<asynchronous suspension>

The error is due to a difference between Dart and RDF Turtle on how single-element-list is represented:

• Dart: [element]
• RDF Turtle: element (i.e., the representation of a single-element-list is the same as an element)
