Since ionic cli 4.10.0 | TypeError: arg.includes is not a function

[iCodr8]

Description:

Since Ionic-cli 4.10.0 I get an error from the cli, when I am building the app for iOS.
With Ionic-cli 4.9.0 or older it is working without any problems.

Steps to Reproduce:

Run ionic cordova run ios -lc --prod

Output:

TypeError: arg.includes is not a function

@iCodr8 Can you check if this is fixed in 4.10.1? Otherwise I may need more information: full command output and ionic info.

@dwieeb It works. Thank you!

@devsgtech You are running on

ionic (Ionic CLI)  : 4.10.0 (/usr/local/lib/node_modules/ionic)

Use npm i -g ionic to update to 4.10.1 as @dwieeb mentioned in his post. Should be working again after the update.

It definitively works with 4.10.1.
