Unexpected key 'input' found

Unexpected key 'input' found, expected one of: acorn, amd, banner, cache, context, dest, entry, exports, external, footer, format,globals, indent, interop, intro, legacy, moduleContext, moduleName, noConflict, onwarn, outro, paths, plugins, preferConst, pureExternalModules, sourceMap, sourceMapFile, targets, treeshake, useStrict, watch

I get this after I updated to 5.x.x

Looks like you don’t have Rollup 0.48 (or higher) installed.

That error message is straight from Rollup, when an invalid key is found in the options object. Very recently the rollup options changed, and input is actually a part of the new structure.

Because this is another breaking change from Rollup…

• karma-rollup-preprocessor@5.0.0 now requires rollup@0.48 (or higher)
• rollup has been made a peer dependency. (So it’s up to you to install it.)

You should try re-installing your node modules, and also install the latest version of Rollup (since the preprocessor no longer does this for you).
