I work with azure-devops-migration-tools version 11.9.20.0.
I am trying to migrate an AZDO project to AZDO.
I created the same methodology structure on the source project, as on the target project.
But the process of migrating work items is entering a disastrous stage.
Here are the logs

Can you help me understand why the sequence contains more than one element?
This issue is solved in this ticket on github. I post the answer here. So it would be helpful for other members who get the same issue to find the solution easily.
In the configuration file, language maps are invalid:
"LanguageMaps": {
"AreaPath": "WorkItems-from",
"IterationPath": "WorkItems-from"
it should be:
"LanguageMaps": {
"AreaPath": "Area",
"IterationPath": "Iteration"
Also its not normal to comment out // "AuthenticationMode": "Prompt",.
