Solution

The problem is that the source environment has broken version sequences in the database. This can happen if they are deleting project versions from the database. In CMJ we are expecting that the sequences of the project version to be the following numbers but if something is deleted not from the Jira UI there are differences in the sequence numbering.

The simplest workaround is to check the sequences in the projectversion Database table and rearrange two versions and then create a new snapshot and try to deploy it.

Here in this example error - we need to rearrange the two versions for the project with this key: EBTRESOSDES and afterward return them to their original state.
