Can't resolve all parameters for TranslateService: (?, ?, ?, ?, ?, [object Object]

Question

I could not test my ionic 3 app in browser anymore since yesterday because I get the following error related to TranslateService. This seems not related to my code sinc

Answer 1

Today we faced the same problem in one of our workstation that shares the same node_module folder with the others! The error seems to be related with the latest Chrome updated version or the generated ts Source Maps or both, because when we were running our apps in dev mode to other browsers were working fine... A quick fix is to do a production build and load it on Chrome , then try again in dev mode. At least this worked for us and maybe will work for others to.

I also have the same version @ngx-translate/core": "^9.1.1" and @ngx-translate/http-loader": "^2.0.1"
