Hi,

just to clarify is this via a 'sync-pack' using the exporter ?

[Nuklon]

I'm not that familiar with the names. What I did: select a node in Umbraco > ... > Do something else > Pull content... (push from other side has the same error) > keep everything selected. Then it loads for a bit (not that long) and this error comes up. If I uncheck most of the stuff below Advanced options it's going through.

Hi, i think you have an old/corrupt setting in your uSync.Publish.config file.

the system exclusions setting stops uSync coping over itself between sites. (and can be configured to not copy other things).

<systemExclusions>bin\\uSync,app_plugins\\uSync,bin\\App_Data</systemExclusions>

these are regex expressions so need the double slash. - i think you might have something in there that isn't a valid expression.

Hi, just to update we might have an issue - checking it now,

we add and exclusion based on project name (based on any *.csproj file in the site root). its possible for us to then get an invalid regex expression loaded. so we might have to clean it up.

[Nuklon]

OK, thanks. I checked systemExclusions on both ends and it seems correct:

  <systemExclusions>bin\\uSync,app_plugins\\uSync</systemExclusions>

My csproj doesn't contain spaces (not sure if that's related though).

[KevinJump]

think i've fixed it but out of interest what is your csproj file name ?

[Nuklon]

It's TestUmbraco8.

[rly-nozebra]

I've got the exact same issue, except the file parsing is bin\MyProjectName

[KevinJump]

yeah - i think it's fixed - we just need to sanitize & text the next release to push it out.

[rly-nozebra]

It seems like it's the automated insert of the project dll in the exclude which misses a \

[KevinJump]

yeah it is. but also we've added a little bit of extra code to clean up any stuff that might get added via config and is incorrect.

@KevinJump Do you have any idea on, when 8.9.3 is released?

[KevinJump]

Hi - it should be today.

We where just halted as we where holding as someone said they had an issue, but i think it turns out they didn't so we should be able to do the checking and release stuff now.

[rly-nozebra]

Cool. Sounds great :-)

[KevinJump]

HI 8.9.3 is released now.
