Issue with Script 7 - Validation Data

[mickymags]

Hello,

I am using the GEE Code Repository authored by Khanal Nishant, found under the tab "Portal User Guide and Manual" at the following link: https://www.landcovermapping.org/en/about/

I have completed 6 of the 7 scripts with no issue, but the final script where we validate the machine learning model and evaluate its accuracy is giving me some issues. Attached please find an image of the error code GEE throws when I run the code. Thanks in advance!

P.S. my validation data was collected through Collect Earth Online and was formatted in the same way as my training data, which was fed into the code in an earlier script with no problem.

This error was due to the fact that my validation data contained a Primitive (aka land cover class) called "unknown".

To all future users, make sure that the validation data you upload as a GEE asset to be used in this script contains ONLY the landcover classes you defined in Script 6 -- Interactive Assemblage (when we created the landcover map).
