Issue/Introduction

Post upgrade to 21.0.5, some clients see forced traces on the CP REST routine as below:
U00045014 Exception 'java.lang.NullPointerException: "null"' at 'com.automic.rest.executions.ert.ErtEstimationResource.computeErtEstimations():79'.
U00003620 Routine 'com.automic.rest.provider.BaseExceptionMapper' forces trace because of error.
U00003450 The TRACE file was opened with the switches '0000000000000000'.
U00003449 Output to the TRACE file is finished.
U00045099 The server replied with following status: '500'

This also sometimes shows without the message:
U00045014 Exception 'java.lang.NullPointerException: "null"' at 'com.automic.rest.executions.ert.ErtEstimationResource.computeErtEstimations():79'.

and shows up as:

U00045098 Method 'GET', URL: '[REST API URL]:[REST API PORT]/ae/api/v1/100/executions/1234567/ert', received from IP: '[IP ADDRESS]'
U00003620 Routine 'com.automic.rest.provider.BaseExceptionMapper' forces trace because of error.
U00003450 The TRACE file was opened with the switches '0000000000000000'.
U00003449 Output to the TRACE file is finished.
U00045099 The server replied with following status: '500'

Forced traces show the following:
