Problems parsing SetParameterAsText

I think I have all my indexing correct.

I have 8 parameters in my script tool. 7 input and 1 derived output. Indexing for GetParameterAsText starts at 0, so logically my SetParameterAsText should have an index of 7, considering my output parameter is the last one in the list.

I use sys.argv to set my input parameters in the script. This index starts at 1.

My script:

How the output parameter is set (there are 8 parameters, I just can't expand the window to show them all):

Input window (don't mind the x's):

Anybody know what could be happening? This is the error I get back:

Traceback (most recent call last):

So, when setting parameter as text, you have to make sure the output is actually a string. In my case it was not, so the script should look like this:

arcpy<SPAN class="punctuation token">.</SPAN>SetParameterAsText<SPAN class="punctuation token">(</SPAN><SPAN class="number token">7</SPAN><SPAN class="punctuation token">,</SPAN> str<SPAN class="punctuation token">(</SPAN>outputPDF<SPAN class="punctuation token">)</SPAN><SPAN class="punctuation token">)</SPAN>‍<SPAN class="line-numbers-rows"><SPAN>‍</SPAN></SPAN>

Makes sense, that would work just fine too.

You're setting the parameter to outputPDF which is a geoprocessing Result object. Set it to outputPath instead.
