I get the following error during installation of the Cordova OneSignal plugin:
UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): [object Object]
DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.
I couldn't find any solutions on Google.

I get this error:
Error: Can't find training file, please try to specify it with the --source option
I thought it was a file path issue, so I added source and still got an error:

I'm working with the Ionic Framework in its 3rd version, and when I run ionic cordova build --release android, I get this error :
(node:13791) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): [object Object]
(node:13791) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.
Other threads about this didn't lead me anywhere. Please help
my first attempt would be to check my code for an unhandled promise rejection.
How can i dectect a unhandled promise rejection?
assuming we have a code like this:
asyncAction.then(success => {
// do stuff with the result of success
})
so if the asyncActions fails, there is an unhandled promise rejection because we never catch the rejection of the promise. To catch the rejection we need to do this:
asyncAction.then(success => {
// do stuff with the result of success
}, rejection => {
// handle action failed
})
I solved my problem downgrading cordova version to 7.1.0
I today run my node js app that i development for months and before it was all excellent..now in console i see this warning errors:

Where can I find what module or function is causing this warning? Because yesterday works all excellent and no code modification is done...where I can search for a problem to fix it? I try to search for Promise in index.js but there is not found...so I think that some npm module is using Promise and how to detect what is it? Does node js have some log text file output that writes in text file description of error what causing it?
