I'm also getting a similar error when pulling. Seems this is because my cloud project has parameters and the CLI didn't recognize them correctly.

I have encountered similar issue. When running "lean cloud pull", the below error messages occurred:

When running "lean cloud push", only projects without built-in parameters can be pushed. Those with parameters generated the same error messages as above.

Many thanks to John and Martin. Problem solved!
