API for progression: The given key was not present in the dictionary

[lotten]

For one specific project in octopus, when I open the overview page i get the following message:
The given key was not present in the dictionary.
I’m running octopus 2019.9.9 LTS.

Logs show the following:

Any idea how to solve that would be appreciated.

Hi @lotten,

Thanks for getting in touch! I’m very sorry to hear you’re hitting this unexpected issue. I’m not currently sure what is causing this, so I’d like to dig deeper. Would you be willing to provide some additional information to help us better understand your environment?

• An export of this single project using the Octopus.Migrator.exe partial-export command
• Output of hitting the releases API endpoint for this project (https://octopus.nl.ohpen.com/api/Spaces-1/projects/Projects-18/releases)

If either of those pieces of information aren’t able to be retrieved due to this issue, would you be willing to provide a full database backup of your instance? The following doc page outlines the process of producing this backup.

How to Get a Database Backup and Encrypt Your Master Key - Octopus Deploy

When logged in to Octopus.com, you can upload these files in your Support tab as shown below.

I look forward to hearing back and getting to the bottom of this one!

Best regards,

Kenny
