… failed transactions
📝 WalkthroughWalkthroughThis PR improves error handling in the Stellar SDK by adding operation context and actionable suggestions to parsed contract errors. It introduces XDR parsing for Soroban transaction results, creates a centralized contract error code mapping system, and updates transaction polling and testing to leverage these enhancements.

In `@ERROR_HANDLING_IMPROVEMENTS.md`:
- Around line 69-75: The example uses FundableStellarError in the catch block
but does not import it, causing compilation errors; update the example to import
FundableStellarError from the SDK (alongside executeWithErrorHandling) so the
instanceof check works—ensure the top of the snippet includes an import for
FundableStellarError (matching the SDK export) and keep the rest of the example
(client.createStream and error.getUserMessageWithSuggestion) unchanged.
In `@packages/sdk/src/utils/errors.ts`:
- Around line 189-243: The parsing/matching is case-sensitive and the caller
only routes errors containing lowercase "simulation" or uppercase "XDR", so
messages like "insufficient fee for transaction" and variants never reach
parseSimulationError; update the caller that decides routing to detect
simulation-related errors case-insensitively (e.g., compare a lowercased error
string and look for "simulation", "xdr", "insufficient fee", "insufficient
balance" etc.), and make parseSimulationError itself use case-insensitive
substring checks (call toLowerCase() once and match against lowercased patterns)
so CONTRACT_ERRORS handling (extractErrorCode) and the checks for "insufficient
fee", "insufficient balance", "contract error", "xdr", and "timeout" catch
common variants; apply the same fix to the other identical block referenced
(lines 275-286).
- Around line 82-141: The contract-specific error branch is checking the wrong
discriminant: it compares firstOp.tr().switch() to
xdr.HostFunctionType.invokeContract(), but firstOp.tr().switch() returns an
OperationType; change that comparison to use
xdr.OperationType.invokeHostFunction() so the Soroban invoke-host-function
operation path is detected. Update the condition in the block that currently
reads firstOp.tr().switch() === xdr.HostFunctionType.invokeContract() to
firstOp.tr().switch() === xdr.OperationType.invokeHostFunction(), leaving the
subsequent invokeResult / sorobanVal / ScVal error handling (and CONTRACT_ERRORS
lookup and getSuggestionForErrorCode) unchanged. Ensure no other enum mismatches
remain in the surrounding logic (e.g., keep
xdr.InvokeHostFunctionResultType.sorobanVal() and xdr.ScValType.error()).
In `@packages/sdk/src/utils/transactions.ts`:
- Around line 145-153: The catch block in transactions.ts currently only
preserves specific RPC errors by matching substrings in rpcError.message; update
it to first check if rpcError is an instance of FundableStellarError and
re-throw it directly (preserving its structured fields), before the existing
message-based guards; locate the catch handling around the rpcError variable and
add an instanceof FundableStellarError branch ahead of the existing checks so
other errors continue to be handled as before.

stellar-sdk OperationResult.tr() discriminant HostFunctionType
💡 Result:
In Stellar's XDR protocol (used across SDKs), OperationResult is a union discriminated by OperationResultCode. When code is opINNER (success case), it contains an OperationResultTr nested union discriminated by OperationType (the original operation type). OperationResult.tr extracts the inner OperationResultTr from an OperationResult when discriminant is opINNER. For InvokeHostFunction operations (type=24), OperationResultTr::InvokeHostFunction contains InvokeHostFunctionResult. HostFunctionType is the discriminant (enum) of HostFunction (used in InvokeHostFunctionOp), not directly in OperationResult. HostFunctionType values: HOST_FUNCTION_TYPE_INVOKE_CONTRACT=0, CREATE_CONTRACT=1, UPLOAD_CONTRACT_WASM=2, CREATE_CONTRACT_V2=3. No evidence of stellar-sdk Rust SDK source with exact OperationResult.tr method found; likely refers to XDR struct access or Java SDK pattern (opInner.getTr). Rust stellar_xdr crate has OperationResult::OpInner(OperationResultTr) with discriminant returning OperationResultCode.

Line 88 compares against the wrong enum—contract error handling will never execute.
firstOp.tr().switch() returns an OperationType discriminant, not HostFunctionType. The comparison should be if (firstOp.tr().switch() === xdr.OperationType.invokeHostFunction()) to detect Soroban invoke-host-function operations. As written, this branch never matches and contract-specific error details are lost, falling through to generic operation-result handling.

Simulation matching currently misses several of the new cases.
Messages like "insufficient fee for transaction" and "insufficient balance" never reach parseSimulationError(...) because the caller only routes errors containing lowercase "simulation" or uppercase "XDR". On top of that, the matcher itself is case-sensitive. The result is that several intended simulation failures still fall back to unknown.

Re-throw FundableStellarError instances directly.
The FundableStellarError thrown on Lines 132-140 is caught again here, and this guard only preserves it when its message matches two hard-coded substrings. Any XDR-derived message such as a contract error or parse failure gets rewrapped as a generic polling error, which drops the structured fields this PR adds.

…ckage This PR's content has been fully absorbed by intervening merges (esp. PR Fundable-Protocol#229's lint/format CI): - main's sdk.yml has lint+format+test+build jobs - main's .eslintrc.json with explicit ESLint v8 + TS rules is in place - main's .prettierrc.json (singleQuote: false, width 80) is established - main's package.json already has lint/format scripts and devDeps Resolution: take main's versions for all conflicted files; drop this PR's .prettierrc (would conflict with main's .prettierrc.json which uses different style settings). Net diff vs main is zero — this PR can be merged as a no-op for attribution, or closed as superseded.

Error Handling Improvements Summary
I have successfully enhanced error handling in high-level clients for failed transactions by implementing comprehensive Soroban simulation error parsing and transaction result XDR decoding to provide human-readable error messages.
Key Accomplishments:
🔧 Enhanced XDR Parsing
🎯 Improved Simulation Error Detection
💡 User-Friendly Error Messages

📁 Files Modified
🚀 Impact
The improvements transform generic technical errors into clear, actionable guidance that helps developers understand what went wrong and how to fix it. Users now receive human-readable messages with specific suggestions instead of raw XDR data or generic error messages.
The work has been committed to the
