I've performed the set of 6 tests as instruction in the GPC documentation. Once packaged and uploaded to the GPC tool, I've received a vague error:
The following errors were reported by the calculation engine:
Error: Fit failed due to data format issues. Check settings, data format and test schedule.
I'm not exactly sure what to check - as far as I can tell, the column mapping is correct, the config file is correct, all the data looks correct.
both the package and report are attached to facilitate troubleshooting.
