Current Behavior

Setup:

1. Export EG manifest from Election Manager
2. Create a key ceremony in EG tablets for election
3. Create election in EG Tablets for election using manifest file
4. Export election artifacts to EGDrive
5. Load election in Scan
6. Insert EGDrive and open polls

Actual Results:

1. There are multiple exceptions in the log: 2022-07-19T13:38:17-06:00|S1701265409|none|65429|Hardware, System, Info|Device|_precomputeInstance.StartPrecomputeAsync(_cipherTextElectionContext.ElGamalPublicKey) 2022-07-19T13:38:22-06:00|S1701265409||none|65429|System, Exception, Error|Exception occurred|Exception details: Exception: The server did not provide a meaningful reply; this might be caused by a contract mismatch, a premature session shutdown or an internal server error.

Impact:

1. High - exceptions are ignored and the polls open and ready to accept ballots so impact unknown

Comments

8/18/2022: Retested after removing the fully disabled contest from the election - issue did not reoccur. Changing the defect to Open because it is still an issue with fully disabled contests
