An unhandled exception occurred: context.getProjectMetadata is not a function

[koczka]

I get this error message, when I try to run my ionic app in the simulator.

An unhandled exception occurred: context.getProjectMetadata is not a function

The command I'm using to run my project (works fine on angular 8, and angular toolkit 2.1)

ionic cordova run ios --livereload --target '...'

Experienced the same issue today. Check your angular package versions in your package.json. For Example mine was like this

"dependencies": {
"@angular/animations": "^9.0.2",
"@angular/common": "^9.0.2",
"@angular/compiler": "^9.0.2",
"@angular/core": "^9.0.2",
"@angular/forms": "^9.0.2",
"@angular/platform-browser": "^9.0.2",
"@angular/platform-browser-dynamic": "^9.0.2",
"@angular/router": "^9.0.2",
...
},
"devDependencies": {
"@angular-devkit/architect": "0.803.14",
"@angular-devkit/build-angular": "0.900.3",
"@angular-devkit/core": "9.0.3",
"@angular-devkit/schematics": "9.0.3",
"@angular/cli": "9.0.2",
"@angular/compiler-cli": "9.0.2",
"@angular/language-service": "9.0.2",

Then I changed them like this after that my problem is solved

"dependencies": {
"@angular/animations": "^9.0.2",
"@angular/common": "^9.0.2",
"@angular/compiler": "^9.0.2",
"@angular/core": "^9.0.2",
"@angular/forms": "^9.0.2",
"@angular/platform-browser": "^9.0.2",
"@angular/platform-browser-dynamic": "^9.0.2",
"@angular/router": "^9.0.2",
...
},
"devDependencies": {
"@angular-devkit/architect": "0.900.2",
"@angular-devkit/build-angular": "0.900.2",
"@angular-devkit/core": "9.0.2",
"@angular-devkit/schematics": "9.0.2",
"@angular/cli": "9.0.2",
"@angular/compiler-cli": "9.0.2",
"@angular/language-service": "9.0.2",

At first I tried variants of 9.0.3 and 0.900.3 but I ecnounted a flattenedMap error. So I changed it to 9.0.2 and 0.900.2 variants. fyi

Yeah, that problem gone away, but I still cannot load the project properly, I always get "Cannot Get /" error now

This solved it for me:
npm install @angular-devkit/architect@latest
npm install @angular-devkit/build-angular@latest
