Description
The README talks about setting the dtype to 'sparseVector', which is an older form of this library. You'd get the error above about "No value found for 'sparseVector'".
The documentation should talk more about how the fields "isSparse": true | false , "dtype": "float", and "isDocumentFeature": true | false are used together to produce the indices and values output and how the naming works. This will allow people to know how to use the library from the documentation without having to go into the tutorial.
In the README, it uses 'words_wideFeatures_sparse', but doesn't give any details.

Research direction
Start with the README section using 'sparseVector' and compare it with the tutorial, which the issue identifies as the more complete source. Document how isSparse, dtype, and isDocumentFeature combine to produce indices and values, explain the words_wideFeatures_sparse naming, and remove the obsolete usage so the README no longer leads to the exception.
