Redmine

I use redmine 5.0.7 with https://github.com/redmine/redmine/commit/d909b82d32fd3deb3b2a01e253da7aa264ffc89c this official patch. When i try to access rest api in json format, i get the error below.
SystemStackError (stack level too deep):
lib/redmine/views/builders/structure.rb:49:in `method_missing'
.......
a lot of this string "lib/redmine/views/builders/structure.rb:69:in `method_missing'"

Without the patch, when i force to install old version of builder gem, rest api works.
