The production metadata derives operationKind from the GraphQL document's AST kind, so normal copied reports begin with values such as Document GetUser rather than identifying the actual query, mutation, or subscription.

sections and mostRecentRequest to choose Markdown fences longer than the longest

closure. Also escape or safely code-format dynamic error text such as typeName
and msg when rendered outside fenced blocks. Add a regression test covering a
standalone backtick-fence line in dynamic content.

Keep the exported return type precise.
getOperationAST(query, operationName)?.operation is typed as OperationTypeNode | undefined in GraphQL 16.14.2. Use this type for getOperationKind and add it to the existing type-only import.

Use a precise type for the test error.
const error: any disables type checking for mostRecentRequest and the DevFatalErrorPage prop. Build the fixture with Object.assign(new Error(...), { mostRecentRequest: ... }) or a local intersection type.
Proposed fix
- const error: any = new Error('Message with `inline` code')
- error.mostRecentRequest = {
- query: ['query GetCode {', ' code', '}', '```'].join('\n'),
- operationName: 'GetCode',
- operationKind: 'query',
- variables: { markdown: '```' },
- }
+ const error = Object.assign(new Error('Message with `inline` code'), {
+ mostRecentRequest: {
+ query: ['query GetCode {', ' code', '}', '```'].join('\n'),
+ operationName: 'GetCode',
+ operationKind: 'query',
+ variables: { markdown: '```' },
+ },
+ })As per coding guidelines, “Prefer precise types and type guards over casts whenever possible.”
