I'm getting the error in the title on a custom track, and this related question ( ['Error in load generator', The provided corpus does not match any of the corpora](https://discuss.elastic.co/t/error-in-load-generator-the-provided-corpus-does-not-match-any-of-the-corpora/185540) ) has no answer.

The track is as follows, operations that have no relation to DATA\_C have been left out:
