Can anyone make sense of this error? I get the error when loading my project and of course when it is run in debug. Apparently a library is missing, but I don;t know which one. If i create a new project, i don't get the error. -Thanks

In general "value cannot be

In general "value cannot be null" means that you have a variable with an empty/null value.

If you need to have a blank value then use a single value mapping or a add new data element to copy over the "empty" variable value.

However in your case it seems you have a dictionary and trying to add a new "entry" but with an empty/null "key" value.

This was quite some time ago,

This was quite some time ago, but I think this was one of those cases where I just had to rebuild my project. I may have caused it when I started deleting some integration libraries.
