this project at McDaniel College and assisting me with this process)


Edgar,

The credentials do indeed belong to an account with administrative permissions 
for this Archon instance, and are valid/correct. The link to the Archon source 
is also valid (we've tried variations with protocol and paths just to make 
sure) as the migration tool proceeds with the first bit of authentication after 
successfully connecting to the Archon source, but ultimately fails and presents 
the error previously mentioned.

I managed to nab a copy of the log before it spits out the error almost 
instantly. Here's what it says:

Administrator authenticated ...
Finding Accession Records Repositories ...
Getting records for: ?p=core/accessions&batch_start=1
No accessions found ...

I hope this helps, thank you.

Failure Message

Hello,

The error seems to point to here: 
https://github.com/archivesspace/archon-migration/blob/v2.3.x/src/org/nyu/edu/dlts/utils/ASpaceCopyUtil.java#L349,
 assuming you are using the 2.3.x version of the migrator.

It could suggest that it did not successfully connect to your Archon instance 
and thus did not return any records causing the Null Pointer Exception. Ensure 
that the Archon user/password combo has administrator privileges, and the 
archon source is the correct URL.

Message

Hello,

We are attempting to migrate from Archon Version 3.21 rev-2.1 to ArchivesSpace 
installation V2.3.0 but we are encountering this error. We have followed up to 
step 5c and 5d in the Archon Migration Tool Instructions and were met with the 
following error.

Can anyone help us interpret this error and figure out where to move forward?

--------

Unrecoverable exception, migration stopped ...
