CMOR.check error in CMORization episode: adding new datasets to ESMValTool

[gulcing]

As explained in the part of "3. Implementing additional fixes" in CMORization episode, when I run this

esmvaltool run recipe_check_fluxcom.yml --config_file <path to config-user.yml> --log_level debug

I got this error:

esmvalcore.cmor.check.CMORCheckError: There were errors in variable GPP:
