Hey,
When filtering a coulmn and the filter contains an apostrophe (using contains and the ODataV4Adaptor) the controller returns an error due to incorectly formatted odata URI as seen here:
$filter=contains(Name, 'tes't')
Just pointing out the bug in case its not on your list of things to fix :)
Screenshot here gives all the details of the error when using the ODataV4Adapter.
Note the apostrophee in the filter input.
I have attached an example project too.
