Plumber returns Error in makeTcpServer, how to troubleshoot?

I am trying to run simple code with plumber

library(plumber)
plumber::plumb("simple_function.R")$run(port = "80")

It returns error:

Running plumber API at http://127.0.0.1:80
Running swagger Docs at http://127.0.0.1:80/__docs__/
Error in makeTcpServer(host, port, private$appWrapper$onHeaders, private$appWrapper$onBodyData,  : 
  Not compatible with requested type: [type=character; target=integer].

It worked this morning just fine. It stopped after installed Docker and build a couple of containers. Any thoughts?

Solution

  • define your port as a numeric

    library(plumber)
plumber::plumb("simple_function.R")$run(port = 80)
