Running into a wall with the CXone data action export endpoint. The Go client keeps rejecting the formatting schema right before the atomic POST. I’ve got the dataset ID references and quote escaping directives locked in. Row limit check triggers a buffer exhaustion failure instead. Here’s the payload for /api/v2/data-actions/export/csv:
The callback handler never fires, so the warehouse sync drops. Logs show the alignment trigger failing on the second iteration without a clear error code.
from purecloudplatformclientv2 import PlatformClient, DataActionsApi, DataActionExportRequest
pc = PlatformClient()
pc.login_client_credentials(CLIENT_ID, CLIENT_SECRET)
api = DataActionsApi(pc)
export_req = DataActionExportRequest(
dataset_id="ds-9921",
delimiter="|",
quote_escape=True,
row_limit=5000
)
resp = api.post_data_actions_export_csv(data=export_req)
You’re still dumping the delimiter into a raw dict instead of instantiating the SDK model? The Go map serialization mangles the JSON schema and throws that 400, so just switch to the typed request object.
The CSV export chokes because the delimiter matrix expects a strict single-character string. It’s the same strict validation you see with WhatsApp HSM templates when variable counts drift.
Cause:
You’re likely injecting an array or a nested object into the delimiter field. The Data Action input contract validates the type strictly. If your upstream JSONPath transform returns ["|"] or wraps the value in a key like {"char": "|"}, the CSV export endpoint throws a 400 immediately. The schema expects a scalar string. When you map nested objects, the JSONPath engine doesn’t auto-flatten. You have to write the path explicitly. Also, that cut-off max field in your snippet suggests you’re hitting the default row limit buffer. The exporter chokes when the payload size exceeds the implicit threshold without an explicit rowLimit defined.
Solution:
Flatten your JSONPath output before the export step. Ensure the transform yields a plain string, not a list. You’ll need to nest the formatting parameters under the correct exportOptions block so the SDK doesn’t strip them out during serialization.
Use the SDK builder if you can. It forces the type checks client-side. If you’re rolling your own JSON, verify the Content-Type header is set to application/json. The API parser ignores the body if the MIME type is wrong. Add Prefer: respond-async to your headers if you’re pushing large datasets. Otherwise, you’ll get a 504 timeout before the CSV generates. The retry logic won’t help if the payload is malformed. Fix the schema first. Stop sending raw dicts and check the input contract documentation.
Dropped the nested object out of the delimiter field and the 400 finally vanished. The endpoint strictly wants a flat string, not an array or a wrapped key. Ran this through Invoke-RestMethod and the CSV export actually queued. It doesn’t choke on the matrix validation anymore. Can’t believe it was just a type mismatch.
Still getting weird truncation on rows past the four-thousand mark though. The row limit parameter seems to ignore anything over that threshold even when the docs say it supports higher caps. Does the scheduler just kill it, or is there a hidden config flag? Server logs show the job starts but then just drops silently. No error payload. Just an empty response.
