Could you elaborate on what you mean by 'instance issues?'

I think this is a good place to start:

If you're looking for answers to specific questions, I'd be happy to help.

This is our list of very best practices. Helps a lot in daily works.
- Always be consistent in naming and follow our naming conventions! Process variables of same semantics are named consistent in all models !
- Always check incoming expression parameters for being NULL or empty !
- Always access CDTs or dictionaries using the index() function !
- Always be consistent in type of returned data. cast(type!YOUR_CDT_TYPE, null) is fine !
- When you get data from queryEntity(), queryRecord() or queryProcessAnalytics(), print it to screen, have a look at it and validate it! Then use it.
- Always pass arguments by keyword. See
forum.appian.com/.../Expressions.html

I think it will depend upon what you mean by issues. Do you mean common syntax problems in SAIL, common install problems, etc.?
Here is a repository of some quick articles to try and explain issues, causes, workarounds, and resolutions of problems that yourself and others may have experienced:
forum.appian.com/.../all.html
You may find something specific to your needs if you encounter an issue with the Knowledge Base section, but if you need something more generalized, like best practices, then the other documentation should be a good reference point.
Hope this helps!
