Migration Tools Problems

I’m trying to use the Migration Tool to copy over a small number of Express Entries from a staging environment to production. Both environments are running current version Concrete, the entities these entries are being migrated between are exactly the same, including the names and handles of entity attributes.

Nonetheless, when I try to load in the the export.xml file into an import batch on the production environment, I get this:

This is occurring, even though the attributes are properly mapped. If I try to import batch to site, I get this:

If I remap the attributes anyway and then rescan, I get this:

At which point, I am basically dead in the water. Nothing else happens past that. Any insight anyone has to offer on this is very much appreciated.

What type of attribute is it? Address or a custom type?

update: I was able to reproduce this. Looks it’s a bug

Made an issue here: Attribute for entity student could not be mapped to a known attribute type · Issue #56 · concretecms/migration_tool · GitHub

not custom attributes-- these entities just have a text attribute used as a name and a text area attribute used as a description. Thanks for your help!
