webMethods Knowlegebase : Maximum JSON request length exceeded

Troubleshooting


Problem

Error while sending a request with greater than 5000000 length.

We have added below setting but still the values show 5000000 in error.

Extended Setting - watt.server.json.decode.maxStringLength = 900000000

custom wrapper - wrapper.java.additional.1100=-DjsonMaxStringLength=900000000
