swagger ui do not shows error body for 4xx return codes

[dambaev]

so when I am trying to update swagger ui, css loader says this:

./node_modules/swagger-ui-dist/swagger-ui.css.webpack[javascript/auto]!=!./node_modules/css-loader/dist/cjs.js??ruleSet[1].rules[4].rules[0].oneOf[0].use[1]!./node_modules/postcss-loader/dist/cjs.js??ruleSet[1].rules[4].rules[0].oneOf[0].use[2]!./node_modules/swagger-ui-dist/swagger-ui.css - Error: Module Error (from ./node_modules/postcss-loader/dist/cjs.js):

which probably means, that we need to update some other dependency. Maybe postcss-loader

UPDATE: postcss-loader update does not solve this error

I had tried to update:

• postcss-loader;
• css-loader;
• webpack;
• build-webpack.

but looks like at this point we need to update angular as it complains now that it was not able to find webpack module. Update of angular is not a fast task, so we need to decide what to do next:

1. try to update angular to get it working with new version of webpack;
2. try to hack current version of swagger to behave with 4xx return codes as with 5xx (with which it shows error body properly). @tphyahoo

@Natsvora : maybe you can check this branch and will see that I do something obvious for angular developer
