How can the error "object 'Uuid' not found" in dplyr when joining dataframes be resolved?

edit

The error "object 'Uuid' not found" in dplyr when joining dataframes can be resolved by checking the column name of the dataset that has 'Uuid' and making sure that it is spelled correctly. It can also be possible that the variable may not be present in the dataframe, so it is necessary to verify that the variable exists in both dataframes before joining them. Finally, if the error still persists, using the as_tibble() function from the tibble package or restarting the R session might resolve the error.
