Most probably CPANTS databases are being regenerated from scratch due to major changes in Kwalitee metrics or updates of relevant modules/perl. Usually this maintenance takes about a day or two, and some of the information may be old or missing tentatively. Sorry for the inconvenience.
Add a README to the distribution. It should contain a quick description of your module and how to install it.
Add a MANIFEST to the distribution. Your buildtool should be able to autogenerate it (eg "make manifest" or "./Build manifest")
Add a META.yml to the distribution. Your buildtool should be able to autogenerate it.
Add =head1 LICENSE and the text of the license to the main module in your code.
Run a proper command ("make manifest" or "./Build manifest", maybe with a force option), or use a distribution builder to generate the MANIFEST. Or update MANIFEST manually.
Error: Cannot find MANIFEST in dist.
List all used modules in META.yml requires

Remove the POD errors. You can check for POD errors automatically by including Test::Pod to your test suite.
Error: Tangle-0.03/lib/CayleyDickson/CayleyDickson.pm -- Around line 573: =back without =over Around line 583: You forgot a '=back' before '=head1'
Add a META.json to the distribution. Your buildtool should be able to autogenerate it.
Define the license if you are using in Build.PL. If you are using MakeMaker (Makefile.PL) you should upgrade to ExtUtils::MakeMaker version 6.31.
Add =head1 LICENSE and/or the proper text of the well-known license to the main module in your code.
Add 'use warnings' (or its equivalents) to all modules, or convince us that your favorite module is well-known enough and people can easily see the modules warn when something bad happens.
