Regression caused by removing namespace_stackable from public API

[bogdan]

Grape removed namespace_stackable from public API. It causes an error:

Error:
TxsAPITest#test_get_tx:
NoMethodError: undefined method 'namespace_stackable' for an instance of Grape::Endpoint

Oh, great catch! I’ll dig into that soon 👍

Hi @bogdan

You’re running against Grape directly from master (the 3.0 work) while grape-swagger hasn’t shipped support for that branch yet. Older releases of grape-swagger also lacked an upper bound on the Grape dependency, so Bundler happily pulled it for the bleeding-edge API and hit the missing namespace_stackable you’re seeing.

I’ve got a #966 that updates grape-swagger to the new inheritable_setting API and bumps the max Grape version to < 4.0. Once that lands (and, probably, after the companion gems like grape-swagger-entity, grape-entity will be updated as well) you’ll be able to run against Grape 3 again.

Thanks for the heads-up!
