Warning: Invalid constructor parameter decorator (es5 to es2015)

[pgarzina]

Hello,

our CI broke when updating ngx-pendo from 1.3.0 to 1.5.1
Using angular 9.
Seems to be an issue because we are using es5 as the target in out tsconfig.json, while if we target es2015 the build compiles.
Since we skipped 1.4.0 I'm not sure when the issue 1st started happening and if this was intentional to ditch es5?

Thanks

Regardless, we'll move our app to es2015, so I guess you can close or delete the issue.

If you want to continue use es5, you can disabled ivy in the tsconfig.
"angularCompilerOptions": { "enableIvy": false }
