There are two separated problems: 1. The validation of sample failed. A sample is not valid if: 1. one of the mandatory fields is missing - you can find the configuration of the mandatory fields in metadata. 2. time stamp is in the future more than x hours as configured in wde settings ( default is 6). 3. customer_name field is missing in sample. 4. customer name does not exist in Customers table in DB. You can see the not valid sample in wdeIgnoredSamples.log. 2. The readPostBody of the http request failed. Something in the http is wrong, the http request returns length that is different from the actual length of the buffer in the http request. Please recheck your http request.
Note these two problems do not happen to the same sample. There are samples that are not valid and there is problem with part of the http requests.
