When preq hits an error, it throws a very generic 504 with no useful diagnostic information:
{
status: 504,
type: "internal_http_error",
detail: "504: internal_http_error",
method: "post",
uri: "https://en.wikipedia.org/w/api.php"
}Log output is similarly unenlightening:
{
"name":"service-mobileapp-node",
"hostname":"mholloway",
"pid":5548,
"level":50,
"message":"504: internal_http_error",
"status":504,
"type":"internal_http_error",
"detail":"504: internal_http_error",
"request_id":"cecc4f80-8961-11e9-bad7-bfcdf067ec2d",
"request": {
"url":"/en.wikipedia.org/v1/page/mobile-sections/Foobar",
"headers":{
"user-agent":"Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:67.0) Gecko/20100101 Firefox/67.0",
"x-request-id":"cecc4f80-8961-11e9-bad7-bfcdf067ec2d"
},
"method":"GET",
"params":{
"0":"/en.wikipedia.org/v1/page/mobile-sections/Foobar"
},
"query":{},
"remoteAddress":"127.0.0.1",
"remotePort":47034
},
"levelPath":"error/504",
"msg":"504: internal_http_error",
"time":"2019-06-07T20:21:18.595Z",
"v":0
}Actually, it appears that error details are being stripped in favor of a redundant message that just restates the status code and type. Removing these lines results in the underlying error message being passed through, which is much more helpful:
{
status: 504
type: "internal_http_error"
detail: "Error: unable to get local issuer certificate"
method: "post"
uri: "https://en.wikipedia.org/w/api.php"
}It looks like a stack trace is also being captured, but not passed through for reasons that aren't clear to me.
