Select By Location in Script Errors

I have no idea why I can run this tool from tool dialogue but not from the following script?

Error Message: Failed to execute. Parameters are not valid. ERROR 000368: Invalid input data.
Failed to execute (SelectLayerByLocation).

I know right?

I was having the same issue with gdb feature classes in doing something similar on this thread

I had to end up running my script in the interactive python window in ArcGIS on the shapefiles I brought into my map that I made converted from gdb feature classes.

Perhaps making a feature layer first from your feature classes then running the select by location tool would work better?

pts_dissolve has to be a feature layer

Making a feature layer before selection corrected my issue. Thank you both! I would probably save a lot of time by reading the resources first. Glad to know I wasn't the only one out there making this mistake. Lol.

@ Ian, I think I solved your gdb quandary...please see your other thread....hope I explained to your satisfaction.

To clarify here, the issue is not the same, although you may argue it could be somewhat related. The issue here raised is 'invalid input' (000368)....and your issues raised are 'invalid parameters' and 'in_features, parameter cannot be set' (000622 and 000628) - I think one tripped the other.

Oh, by the way, I made an error in the earlier script anyway - and I think your suspicions were well-founded about the lock...I'm still not fully satisfied I understand it, but the workaround is sound.
