    Import results in error - Unexpected character encountered while parsing value

    uSync
    Umbraco 7

    We're using uSync ((uSync.BackOffice 4.0.14.0) (uSync.Core 6.0.14.0) [uSync.Content: 4.1.8.0]) on an Umbraco 7.15.3 site. Our intention is to allow our editor to make back office changes in our dev environment and then use uSync to migrate those edits into our test environment (and ultimately to prod if this works out).

    We've turned off import on start.

    When we migrate the updated uSync files from the dev environment to the test environment and run the Report to see the changes it correctly picks up the changes to be applied. However, when we Import (either just the changes or a full import) the following error is being thrown:

    "Error: An error has occurred. - Unexpected character encountered while parsing value: <. Path '', line 0, position 0."

    Something is having trouble parsing the JSON in the uSync files. I can post a full call stack if necessary.

    Does anyone know what might be the issue? This is a relatively new site - we're not dealing with 2 separate databases with huge content/data type differences between them.

    Hi,

    can you isolate which .config file is causing the issue?

    if not first try turning logging up by adding the following to the log4net.config file 

    <logger name="Jumoo.uSync">
  <level value="DEBUG" />
</logger>

    if you can, feel free to post that file. As you say it's probably a bit of JSON parsing somewhere - but if we can isolate it - we should be able to fix it quicker.

    Hi Kevin,

    I've set the Jumoo namespace to DEBUG logging as indicated and re-ran the import. Here's the call stack from the log.

    If I'm reading the stack correctly then the last Importing Content statement logged before the error was
