Release
All
Cause
The limitation set in the system property mid.eccq.max_payload_size.
Specifies the maximum string length of a payload that the MID server sends to the instance. The MID Server verifies the size of the payload before sending it to the instance, If the payload size exceeds the limit, the MID Server discards it and returns an error message in the payload.
Resolution
1) Go to MID Server > Select the MID server where the REST call is going through> Under the related list, go to MID Properties.
2) Check if the property mid.eccq.max_payload_size does exist.
3) If the property exists, increase the size of the payload in bytes, if it doesn't exist create new and specify the payload size in bytes, default is 20000000 bytes.
OR
1) you can also configure this as a configuration parameter on an individual MID Server
2) Please follow the below documentation to configure the parameter on specific MID Server
