Uncaught SyntaxError: Unexpected end of JSON input

I am getting this error on reload of the client, otherwise seems to work.

Server is running origin/cardano-sl-1.0 front end is running daedalus master

Here is where it is happening in request.js

   response.on('end', () => {
        const parsedBody = JSON.parse(body);

The this.req.res.statusCode== 404 and is not being checked.

Now there are two files that look very similar: https://github.com/input-output-hk/daedalus/blob/master/app/api/etc/lib/request.js#L36 and https://github.com/input-output-hk/daedalus/blob/master/app/api/ada/lib/request.js#L75

Body is empty:

The incoming message is a 404 not found!

IncomingMessage {_readableState: ReadableState, readable: false, domain: null, _events: EventHandlers, _eventsCount: 3…}
statusCode:404
statusMessage :"Not Found"

The request is “/api/settings/time/difference”

Here is what I found in the _header : .req.socket._httpMessage._header

“GET /api/settings/time/difference HTTP/1.1 Host: localhost:8090 Connection: close”

the api is there is in the unreleased version I am using. https://github.com/input-output-hk/cardano-sl/commit/58bd3caab1779b2cd71f0298bc18f766cdd80ab8#diff-1cd0b0acca347cce42b9aea9b5122eed

See https://github.com/input-output-hk/cardano-sl/blob/429efc2426c63802ae86789f5b828dcbb42de88a/wallet-new/README.md

Currently the only way to generate an updated swagger.json is to run the wallet-new-server node, so that the updated Swagger file will be written on disk. For example:

stack exec wallet-new-server -- --topology=wallet-new/topology-examples/testnet.yaml \
  --configuration-key mainnet_staging_short_epoch_full --wallet-debug --rebuild-db

This issue is no longer reproducible in the latest Daedalus version.
