Why does this setting block WFM data sync during load?

Running a JMeter script to stress-test the Workforce Management API. The sync job fails with a 500 Internal Server Error when concurrent requests exceed 50. This seems unrelated to the actual WFM logic.

• Checked the standard rate limit headers; no 429s observed before the crash.
• Verified the payload structure against the documentation; it matches perfectly.

Any ideas on the hidden capacity limits for the /api/v2/wfm/data endpoint?

If I recall correctly, the wfm api has a strict concurrent request cap of 50 per tenant. add a think_time in your jmeter script to throttle the requests and see if the 500s stop.
