Session ends during exporter starts

[cheeye]

Describe the bug
During the exporter starts, it enables all available cpc objects. But it ends when it hit an exception. I didn't get such issue with v1.7.1.

.....
Enabling auto-update for storage volume V5K_DATA_0_LPAR_27.100.00 GiB Data
Enabling auto-update for storage volume v840_lpar04_data_01.200.00 GiB Boot
Enabling auto-update for storage volume V5K_ROOT_LPAR_19.1200.00 GiB Data

Closing session with HMC

Expected behavior
Continue enabling all the rest objects

To Reproduce
Start exports

Hello @cheeye . The HTTP status code 500 reason code 12 is not something the HMC should return. The exporter has no other chance than giving up when it gets that.

Could you please open a PMR for that error? That allows the Z firmware team to analyze the problem.

I am pretty confident that exporter version 1.7.1 would also give up when it encounters that situation. If the issue is reproducible with exporter version 2.0.0, can you please run version 1.7.1 against the same HMC and see whether the problem occurs with that version, too?
