[pickWaveAction] requestedCount must be a positive integer…

Error message

[pickWaveAction] requestedCount must be a positive integer; got ${args.requestedCount}

What it means

Argument validation in pickWaveAction: requestedCount is not a positive integer (zero, negative, fractional, or NaN). The requested wave size drives sampling and Resend segment creation, so an invalid count is rejected before any state is touched.

Solutions

1. Pass a positive integer requestedCount matching the ramp tier's wave size
2. Validate the count at the caller (ramp runner config) before dispatching the action

When it happens

Trigger: Thrown at convex/broadcast/waveRuns.ts:701 when the library encounters an invalid state.

Common situations: See trigger scenarios.
