Problem: Issue starting Semaphore server after v2.14.0

[guyke01]

Issue

After upgrading to version v2.14.0 or higher the Semaphore server is not booting anymore. The following error is being generated in the logs:

cannot assign value of type string to map element of type null

After reverting to v2.13.15 the container boots again but due to the DB migration some things don't work.

Hi @guyke01 please try https://github.com/semaphoreui/semaphore/releases/tag/v2.14.5

I hope it solves the issue, but I'm not sure.

[guyke01]

Hi @fiftin I've used the tag v2.14.5 and started the container but got the same error

@guyke01 can you check database table option? Do you something strange in it?

[guyke01]

@fiftin this is the export of the option table

+--------------------------+---------------+
| key                      | value         |
+--------------------------+---------------+
| apps.ansible.active      | true          |
| apps.powershell.active   | true          |
| apps.powershell.icon     | powershell    |
| apps.powershell.order    | 0             |
| apps.powershell.priority | 0             |
| apps.powershell.title    | Powershell    |
| apps.python.active       | false         |

| apps.terraform.active    | false         |
| apps.tofu.active         | false         |
+--------------------------+---------------+

I see there is a value null in the key apps.python.args. After i delete the value the following error appears:

panic: cannot assign value of type string to map element of type

Is there something i need to delete in the table?

[guyke01]

After i deleted the row apps.python.args the container started again and works now. The issue is solved!

[fiftin]

Thank you @guyke01 ! It is really helpful answer! null string shouldn't be parsed as null. I will try to reproduce soon.

And I fixed another issue with nullable value column (now it not null), haha ))
