Angular Nightmare: “Invalid ICU message. Missing }.ngtsc(-995002)” Error Solved!

• Missing or misplaced curly braces in ICU messages
• Incorrect syntax in the message format
• Outdated Angular or dependencies
• Conflicting plugins or libraries

Solution 1: Check for Missing Curly Braces

Let’s start with the most obvious culprit: missing curly braces. Take a closer look at your ICU messages and ensure that every opening curly brace ({) has a corresponding closing curly brace (}).

{ count, plural,
  =0 {no items}
  one {one item}
  other {# items}
}

In the example above, the ICU message is correctly formatted with opening and closing curly braces. Double-check your code to ensure that all messages follow this pattern.

Solution 2: Verify Message Format Syntax

Next, let’s examine the syntax of your ICU message format. Make sure you’re using the correct syntax for the specific type of message you’re working with.

Simple Messages

{ msg }

Plural Messages

{ count, plural,
  =0 {no items}
  one {one item}
  other {# items}
}

Select Messages

{ gender, select,
  male {He}
  female {She}
  other {They}
}

Take a closer look at the official Angular documentation for ICU message formats to ensure you’re using the correct syntax.

Solution 3: Update Angular and Dependencies

Outdated Angular or dependencies can sometimes cause issues like the “Invalid ICU message” error. Make sure you’re running the latest versions of Angular and its dependencies.

ng update @angular/core @angular/cli

Run the above command in your terminal to update Angular and the CLI. This might resolve any compatibility issues that could be causing the error.

Solution 4: Disable Ivy Compiler

In some cases, the Ivy compiler can be the source of the issue. Disabling it might help resolve the error. However, keep in mind that this is a temporary solution, and you should aim to fix the underlying issue.

"angularCompilerOptions": {
  "enableIvy": false
}

Add the above configuration to your `tsconfig.json` file to disable the Ivy compiler.

Solution 5: Check for Conflicting Plugins or Libraries

Finally, let’s investigate if any conflicting plugins or libraries might be causing the issue. Try to isolate the problem by disabling or removing suspected plugins or libraries.

For example, if you’re using a third-party library that integrates with Angular, try disabling it or updating it to the latest version.

Conclusion

By following these steps, you should be able to resolve the frustrating “Invalid ICU message. Missing }.ngtsc(-995002)” error in your Angular project. Remember to:

1. Check for missing curly braces in ICU messages
2. Verify the syntax of your ICU message format
3. Update Angular and dependencies
4. Disable the Ivy compiler (as a last resort)
5. Check for conflicting plugins or libraries

With these solutions, you’ll be well-equipped to tackle this error and get your Angular project back on track. Happy coding!
