Use this table to diagnose and resolve issues: + +| Code | Error Variant | When Triggered | How to Fix | +|------|--------------|----------------|------------| +| 1 | `InvalidAmount` | Amount is zero, negative, or out of range | Provide a positive, non-zero amount within token limits | +| 2 | `StreamNotFound` | No stream exists for the supplied ID | Verify the stream ID exists using `get_stream()` | +| 3 | `Unauthorized` | Caller lacks permission for this action | Ensure the caller is the stream sender or recipient | +| 4 | `StreamInactive` | Operation requires an active stream | Check stream is not cancelled or completed | +| 5 | `AlreadyInitialized` | `initialize()` called more than once | Protocol is already initialized, no action needed | +| 6 | `NotAdmin` | Caller is not the protocol admin | Use the admin account for this operation | +| 7 | `InvalidFeeRate` | Fee rate exceeds 1,000 bps (10%) | Reduce fee to ≤1,000 basis points | +| 8 | `NotInitialized` | Protocol config not initialized | Call `initialize()` first | +| 9 | `InvalidDuration` | Duration is zero | Provide a positive duration in seconds | +| 10 | `InvalidTokenAddress` | Token address is not a valid token contract | Verify the token contract address | +| 11 | `InvalidRate` | `amount / duration` rounds to zero | Increase amount or decrease duration | +| 12 | `StreamPaused` | Operation requires active (non-paused) stream | Resume the stream first using `resume_stream()` | +| 13 | `StreamNotPaused` | `resume_stream()` called on active stream | Stream is not paused, no action needed | +| 14 | `StreamAlreadyPaused` | `pause_stream()` called on paused stream | Stream is already paused | +| 15 | `ProtocolPaused` | Circuit breaker is engaged | Wait for admin to unpause the protocol | +| 16 | `EmptyVestingSchedule` | Step-tranche schedule has no steps | Provide at least one vesting step | +| 17 | `TooManyVestingSteps` | Schedule exceeds `MAX_VESTING_STEPS` | Reduce number of steps | +| 18

must have positive amounts | +| 20 | `VestingStepTotalMismatch` | Step amounts don't sum to deposit | Adjust steps to match deposited amount | +| 21 | `VestingStepBeforeStart` | Step unlocks before stream start | Schedule all steps after start time | +| 22 | `InvalidCliffParameters` | Cliff configuration is invalid | Ensure cliff is after start and leaves room for linear tail | +| 23 | `BatchTooLarge` | Too many stream IDs in `batch_withdraw()` | Reduce batch size to ≤`MAX_BATCH_WITHDRAW` | +| 24 | `NotGuardian` | Caller is not admin or guardian | Use admin or emergency guardian account | +| 25 | `UnsupportedMigration` | Migration to unsupported version | Check compatible migration versions | +| 26 | `StateVersionTooNew` | On-chain state is newer than contract | Deploy newer contract version | +| 27 | `TopUpUnsupported` | Top-up called on step-tranche stream | Top-ups only work on linear/cliff streams | +| 28 | `RateModificationUnsupported` | Rate change on unsupported schedule type | Rate modifications only for linear streams | +| 29 | `InvalidNewRate` | New rate is zero or too small | Provide a valid positive rate | +| 30 | `DisputeNotSupported` | Dispute on non-disputable stream | Stream was not created with dispute support | +| 31 | `NoActiveDispute` | No active dispute to resolve | Create a dispute first | +| 32 | `NotArbiter` | Caller is not the dispute arbiter | Use the designated arbiter account | +| 33 | `AllowanceLocked` | Allowance-based operation failed | Check token allowances are sufficient | +| 34 | `ArithmeticOverflow` | Calculation exceeded i128/u64 range | Reduce amount or duration to avoid overflow | +| 35 | `StreamNotActive` | `resume_stream()` on inactive stream | Can only resume active streams | +| 36 | `StreamStillActive` | `close_stream()` with funds remaining | Withdraw all funds or cancel stream first | +| 37 | `InvalidMilestone` | Milestone ID invalid or duplicated | Check milestone IDs are unique and exist | +| 38

errors (#3, #6, #24, #32, #43) mean you're calling from the wrong account.
