> > There is an error message `Matches multiple schemas when only one must validate.` but it smells a limitation on yaml Language server. it seems there is a workaround to shut ignore the error in the yaml language server especially for that for Kubernetes schema https://github.com/redhat-developer/yaml-language-server/blob/8f8a4c52363d2c8c003e08b12cb7db97550afbca/src/languageservice/services/yamlValidation.ts#L91 > > in fact, it seems that it is coming from https://github.com/microsoft/vscode-json-languageservice/blame/fad098244642100e5054dedefed9da905b24aedc/src/parser/jsonParser.ts#L458 and Yaml Language Server has put a workaround flag to ignore this error. > > If i understand well, this message is provided when several different elements are matching the same tag. > I found that several json schema has been modified to avoid that it occurs but wasn't able to find a pattern on how they fixed it. > For Kubernetes, it seems that they just put the silent mode at Yaml language Server level. as suggested here https://github.com/microsoft/vscode-json-languageservice/issues/60#issuecomment-652753506 using `anyOf` instead of `oneOf` should avoid the warning. From what I understand of the difference between the two is only at validation where the `oneOf` is that we want a single possible schema. http://json-schema.org/draft/2019-09/json-schema-core.html#rfc.section.9.2.1.2 <pre><code> 9.2.1.2. anyOf This keyword's value MUST be a non-empty array. Each item of the array MUST be a valid JSON Schema. An instance validates successfully against this keyword if it validates successfully against <b>at least one schema</b> defined by this keyword's value. Note that when annotations are being collected, all subschemas MUST be examined so that annotations are collected from each subschema that validates successfully. 9.2.1.3. oneOf This keyword's value MUST be a non-empty array. Each item of the array MUST be a valid JSON Schema. An instance validates successfully against this keyword if it validates successfully against <b>exactly one schema</b> defined by this keyword's value. </pre> so i think that we need to use `anyOf` instead of `oneOf` in our case. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
