[BUG] Upgrade from 7.0.0 to 7.5.x/8.x on Angular 18 will not compile

[Austinb]

Environment

Please provide as many details as you can:

• Hosting type
  • [] Form.io
  • Local deployment
    • Version: 7.5.x or 8.x
• Formio.js version: N/A
• Frontend framework: Angular 18.2.x using @angular-builders/custom-esbuild
• Browser: N/A
• Browser version: N/A
• Typescript 5.5.4

Steps to Reproduce

This is an upgrade from Angular 17 to Angular 18.2 and upgrading formio/angular from 7.0.0 to 7.5.x or 8.x

Expected behavior

Expect app to compile and run using ng serve {app}

Observed behavior

Application will not compile for ng serve {app}. Throws errors referencing @formio/deprecated-types which is not mentioned in the installation instructions but is fixable. Main issue is the cascade of other errors which appear to be missing dependencies being thrown from pretty much every .ts file within the node_modules/@formio install directory. Unsure if the formio/angular library is expecting other dependencies or what. Rolling back to 7.x with overrides compiles as expected and the usage works as expected within the compiled app.

Also, it does not seem to matter what version of formio/js is installed or bootstrap which is also used.

Example

Running ng serve {app} results in the following errors plus many more being displayed in the console

I've had the same issue with Angular 18.2 and version 8.x

This user has gotten the same error:
formio/formio.js#5993

Hi. We're running into the same issue as originally posted. I would be nice if this gets resolved since starting a new project on Angular 17 is no longer an option given LTS end date for it.

Hello, i suggest you to check out formio/formio.js#5715 (comment) as it should be fixed
