45210: Flex Flow creation failed

This error means Flex could not create the Flex Flow. Most often, the create request is missing required parameters, contains invalid values, or conflicts with an existing Flex Flow configuration.

• The request did not include one or more required parameters such as friendlyName, chatServiceSid, or channelType.
• The channelType value is not supported. Flex Flow creation supports web, sms, facebook, whatsapp, line, and custom.
• The request used integrationType without the matching integration settings. studio requires integration.flowSid, external requires integration.url, and task requires integration.workspaceSid, integration.workflowSid, and integration.channel.
• One or more request attributes conflicted with an existing Flex Flow.

• Include all required top-level fields in the create request. At minimum, send friendlyName, chatServiceSid, and channelType.
• Verify that channelType and integrationType use supported values only.
• If you use studio, external, or task, add the required integration fields for that integration type before you retry the request.
• Review the error details returned in the API response, then correct the invalid or missing fields and submit the request again.
• If the request conflicts with an existing Flex Flow, update the new Flow configuration so it does not overlap with an existing one.
