TypeError: res.status is not a function

[sv2]

TypeError: res.status is not a function at trackingMiddleware (/usr/src/app/node_modules/swagger-stats/lib/swsInterface.js:345:21)

when I try to access the ui.

I have deployed my node app in a docker container on kubernetes

http://disq.us/p/1up1rhr

[akitto69]

interestingly if run the app locally (not in the docker container) http://localhost:8400/swagger-stats/ui

I get the following

Cannot GET /swagger-stats/ui

The full error when I deploy in the docker container is

TypeError: res.status is not a function at trackingMiddleware (/usr/src/app/node_modules/swagger-stats/lib/swsInterface.js:345:21) at call (/usr/src/app/node_modules/connect/index.js:239:7) at next (/usr/src/app/node_modules/connect/index.js:183:5) at Function.handle (/usr/src/app/node_modules/connect/index.js:186:3) at Server.app (/usr/src/app/node_modules/connect/index.js:51:37) at emitTwo (events.js:126:13) at Server.emit (events.js:214:7) at parserOnIncoming (_http_server.js:619:12) at HTTPParser.parserOnHeadersComplete (_http_common.js:112:17)

with debug on deployed in the docker container

when running local the following debug is output sws:apistats SWS:Initialize API:added get /open-banking/v1.1/banks (/open-banking/v1.1/banks) +0ms sws:apistats SWS:Initialize API:added post /open-banking/v1.1/payments (/open-banking/v1.1/payments) +2ms sws:apistats SWS:Initialize API:added get /open-banking/v1.1/payments/{PaymentId} (/open-banking/v1.1/payments/:PaymentId) +1ms sws:apistats SWS:Initialize API:added post /open-banking/v1.1/payment-submissions (/open-banking/v1.1/payment-submissions) +0ms sws:apistats SWS:Initialize API:added get /open-banking/v1.1/payment-submissions/{PaymentSubmissionId} (/open-banking/v1.1/payment-submissions/:PaymentSubmissionId) +0ms sws:elastic Elasticsearch is disabled +0ms

but I still have the following Cannot GET /swagger-stats/ui

[akitto69]

I am using "prom-client": "11.1.1" at the same time could that cause a conflict?

[akitto69]

remove prom-client and tested still getting the same results when running locally

Looks like req and res arguments passed to swagger-stats middleware could be wrong. Which version of express are you using ? Could you share your package.json ?

the code I have used in my index.js is as follows let apiSpec = require( './api/swagger.json' ) let swaggerStats = require('swagger-stats') app.use(swaggerStats.getMiddleware({swaggerSpec:apiSpec}))
