Wfm schedule import 400 bad request on custom fields

Just noticed that the schedule import job is failing with a 400 bad request when pushing data from servicenow via the wfm api. the endpoint is /api/v2/wfm/schedules/import. the payload looks correct based on the swagger docs but the response body says “invalid value for field ‘agent_skills’.” we are using the data action framework to map the servicenow incident fields to the wfm schedule object. the environment is eu-west-1 and we are on the latest release. i have checked the field mappings in the data action and they match the schema defined in the wfm settings. the error occurs specifically when the agent has more than one skill assigned. if i remove the extra skills it works fine. is there a limit on the number of skills per agent in the import payload? or is this a known issue with the array format in the json body? the request id in the header is 12345-abcde. logs show no further details. any help would be appreciated. we need this fixed before the next pay run. the timezone is london so the schedule start times are utc+1. the servicenow instance is wash dc. the data action version is v2. the conversation trigger is set to create schedule. the screen pop is not involved here. just the api call. the webhook returns 200 but the background job fails. the error message is generic. no stack trace. just the field name. i have tried escaping the characters. no change. the json is valid. validated in jsonlint. the array is comma separated. quotes around strings. numbers are not quoted. the skill ids are correct. verified in the admin console. the agent ids are correct.
