Yarn failing in alpine (edge)

[eine]

As commented in filebrowser/filebrowser#530 yarn is failing in golang:alpine with edge (the development tree). These are the differences between v3.8 and edge:

(1/17) Installing nghttp2-libs (1.33.0-r0)
(10/17) Installing libcrypto1.0 (1.0.2p-r0)
(13/17) Installing libssl1.0 (1.0.2p-r0)
(15/17) Installing libuv (1.22.0-r0)
(17/17) Installing yarn (1.9.4-r0)

(1/17) Installing nghttp2-libs (1.32.0-r0)
(10/17) Installing libcrypto1.0 (1.0.2o-r2)
(13/17) Installing libssl1.0 (1.0.2o-r2)
(15/17) Installing libuv (1.20.2-r0)
(17/17) Installing yarn (1.7.0-r0)

Moreover, yarn 1.9.4 works ok if installed manually on v3.8. So the source of the problem should be in any of the other.
