yaml extension error ( Incorrect type. Expected "string".yaml-schema: pubspec.yaml )

enter image description here

Recently I created a flutter project and opened the "YAML", getting some error from "YAML" extension. How can I solve this? Is the only solution to uninstall the extension or how to overcome this without uninstalling this extension?

Tried flutter clean, repair, etc. but nothing was helpful.

Errors are:

1 Incorrect type. Expected "string". yaml-schema: pubspec.yaml

2 Property flutter is not allowed. yaml-schema: pubspec.yaml

3 Property cupertino_icons is not allowed. yaml-schema: pubspec.yaml

4 Property flutter_test is not allowed. yaml-schema: pubspec.yaml

5 etc.

Using flutter version is 2.8.1

"YAML" (extension) version v1.5.0

Removing Yaml extension did the trick for me, in fact I don't really see the need for it since VS Code supports YAML formats by default

Please update VSCode's YAML extension to at least 1.5.1 to resolve the error. Flutter will work as it is with the errors too.

I fixed mine by reloading the extension. I went to my extensions tab and the YAML extension needed to be reloaded.

It does not show here but instead on the left of "Disable", there was a message telling me that I needed to reload the extension.

For me, in the extensions of VsCode, I looked for YAML and I saw there is a "reload required" next to it. did the reload and the errors went away. It is all fixed now.

I'm having the same issue with VSCode since this afternoon, everything worked well before. I've tried forcing the schema via # yaml-language-server: $schema=<urlToTheSchema> and yaml.schemas setting, but no luck.

Edit: could be related to upgrading to yaml extension v1.5.0 (cf: https://github.com/redhat-developer/vscode-yaml/issues/708) Temporarily downgrading back to 1.4.0 no longer throws errors.

The YAML extension is using an incorrect schema to validate your YAML file. Ensure that:

  • your file does contain a correct # yaml-language-server: $schema=<urlToTheSchema> comment or at least does not contain a wrong one.
  • your yaml.schemas setting does not associate your file via glob pattern with an incorrect schema.

The correct schema would be https://json.schemastore.org/pubspec.json. See also Associating Schemas.
