  Based on your description and the error logs, the issue is related to ABP Suite's handling of the solution configuration, specifically a NullReferenceException when accessing the MigrationsMigrationsDbContext property. This is likely caused by a missing or corrupted configuration in the ABP Suite's appsettings.json for your solution, which can happen if the configuration file is out of sync or incomplete on some developer machines.

  Your workaround—manually updating the configuration in ABP Suite's appsettings.json with the correct paths and values—directly addresses this. This ensures that ABP Suite can properly locate all required projects and context files, preventing the null reference error.

  Recommended Steps:

  1. Ensure all developers have the same, up-to-date configuration block for the solution in their ABP Suite appsettings.json.
  2. Double-check that all paths in the configuration are correct and point to valid locations on each developer's machine.
  3. If the error recurs, remove the solution entry from appsettings.json and re-add it using the working configuration.

  For more details on configuring and troubleshooting ABP Suite solution settings, refer to the official documentation:

  • ABP Suite Configuration

  This approach aligns with ABP Suite's expected configuration management and should resolve the issue for all team members.

  Thanks, bot! 🙂 ABP team, I reported this so you can take a look, as it could become a time-consuming issue if all three developers are experiencing the same problem. I hope the information provided is enough to investigate. If not, I’d be happy to show you the issue live by sharing my screen, just let me know.

  Hi, sorry for the bot's response, it sometimes helps :)

  Thanks for the detailed information and sharing the appsettings.json file with the error logs, this helps a lot to identify the problem.

  [ERR] Error getting value from 'MigrationsMigrationsDbContext' on 'Volo.Abp.Suite.Models.Solution'.

  Before you update the appsettings.json file, do you remember the value of the MigrationsMigrationsDbContext field? Also, I will create a tiered solution and try to understand the problem better, but by any chance, can you also share the not-updated (default) values of the appsettings.json file, so I can see the changes and check at the code level? (I'll try to identify at which point ABP Suite is currently unable to determine the related path)

  Regards.

  No, sorry... we don't have the previous appsettings.json. When we encountered the issue, we removed the solution from ABP Suite and tried to add it again (also without success). What we can share with you (preferably in an online meeting) are the error messages and logs we get when trying to add or open the solution in ABP Suite (after removing the solution from ABP Suite). That might be a quicker way for you to troubleshoot the issue.

  Thanks for the update. Actually, I've created a tiered application just before and will try to reproduce it on my side. If i can't do it, I might need your help, I'll let you know.

  Thanks again. Regards.

  Hi! I just reopened what the bot closed :) Just a reminder of something that I realized and wrote in my fist comment: "I do not see the option to get the solution configuration with ABP Studio, the button is not visible now" I created a new solution with ABP Studio and the option "Solution Configuration" is available

  Hi, this feature was added with v0.7.6+, and it basically puts configuration into your *.abpsln file while creating an application (section name: creatingStudioConfiguration). So, probably your solution was created before v0.7.6 and this is the reason why you don't see the "Solution Configuration" context menu item.

  OK! this is our abpsln file, in case it helps:

  {
    "id": "fff39d08-98bc-4ab2-9e28-c05a141732a2",
    "template": "empty",
