Error: Cannot read properties of undefined (reading 'filter')
Description
Encountered an unhandled TypeError during the execution of updateDiagnostics
function in the TypeScript error translator extension for VSCode. The error suggests an issue with reading properties of an undefined object, specifically when attempting to filter diagnostics.
Error Details
- Type: TypeError
- Message: Cannot read properties of undefined (reading 'filter')
-
Location:
updateDiagnostics
function at/Users/jobayerhossain/.vscode/extensions/mattpocock.ts-error-translator-0.10.1/out/extension.js
line 61730:36 - Handled: No
Stack Trace
TypeError: Cannot read properties of undefined (reading 'filter')
at /Users/jobayerhossain/.vscode/extensions/mattpocock.ts-error-translator-0.10.1/out/extension.js:61730:36
Code Snippet
try {
// Existing code that might throw an error
} catch (e) {
// Error handling
}
helperDiagnostics.set(
document2.uri,
uriStore[document2.uri.path].filter(tipHasNoDepsOrAllDepsCompleted).filter((tip) => !isTipComplete(tip.type)).map((tip) => {
const diagnostic = new vscode5.Diagnostic(
tip.range,
tip.type,
vscode5.DiagnosticSeverity.Information
);
diagnostic.source = "total-typescript";
return diagnostic;
})
);
Potential Issue
The error appears to be related to the assumption that uriStore[document2.uri.path]
is always defined and can be filtered. This may not be the case, leading to the TypeError when attempting to call .filter()
on an undefined object.
Steps to Reproduce
- Install the TypeScript error translator extension (version 0.10.1) in VSCode.
- Trigger the
updateDiagnostics
function under conditions that lead touriStore[document2.uri.path]
being undefined.
Expected Behavior
updateDiagnostics
should handle cases where uriStore[document2.uri.path]
is undefined, avoiding any TypeErrors related to calling .filter()
on undefined.
Actual Behavior
The application throws a TypeError when it attempts to filter on an undefined object within the updateDiagnostics
function.
