xConnect install: Property "errorMessages" cannot be found on this object

Question

I'm trying to install the XP0 local development version of Sitecore using George Chang's blog as a reference: https://blogs.perficient.com/microsoft/2017/10/how-to-install-sitecore-9-with-the-sitecore-install-framework. I saved the Sitecore Install Framework downloads to one PS1 file, and the XP0 install scripts to a second file.

I had to increase the Solr start timeout to get past a checking error (from 8000 to 20000) but everything else was working until I got to this point in the xConnect XP0 install. From the xconnect-xp0 log file:

TerminatingError(Invoke-ManageSolrSchemaTask): "The running command stopped 
because the preference variable "ErrorActionPreference" or common parameter is set 
to Stop: The property 'errorMessages' cannot be found on this object. 
Verify that the property exists."

Right before that error hit, this was the logged content (to provide context to which step it's failing at):

VERBOSE: Performing the operation "Invoke-ManageSolrSchemaTask -Address https://localhost:8983/solr -Core sc90_xdb" on target "https://localhost:8983/solr".
[ConfigureSolrSchemas [1]]:[Schema] Modifying Schema on https://localhost:8983/solr : sc90_xdb
VERBOSE: Updating Solr Schema: Uri => 'https://localhost:8983/solr/sc90_xdb/schema?wt=json'
VERBOSE: POST https://localhost:8983/solr/sc90_xdb/schema?wt=json with -1-byte payload
VERBOSE: received 184-byte response of content type text/plain;charset=utf-8

This has happened a couple of times, so I'm not sure what the sticking point is. Solr is running just fine, and at the point of failure I see the two sc90_xdb cores (main and rebuild).

I'll have to test this locally, but it could be a change in the response from Solr in 6.6.2 compared to 6.6.1. It's looking for errorMessages to check if there were errors when calling solr and actually failing as the member does not exist.

As a temporary measure, you can tell SIF to continue on error by adding the following to the parameters for the task "ErrorAction": "Continue"

This will enable SIF to continue processing when this task throws an error.
