Error when testing lesson

[almas2019]

@souravsingh I receive the following error when testing lesson 1:
Error in yaml.load(readLines(con), error.label = error.label, ...) :
(/Library/Frameworks/R.framework/Versions/4.0/Resources/library/swirl/Courses/BiocSwirl_Intro_to_Stats/lab01_correlation/lesson.yaml) Scanner error: mapping values are not allowed in this context at line 16, column 70

I think there might be a mistake in the Yaml file
