trans_env class error

[HCB-M2RG]

Hello I received this error when working with the trans_env class when running this command:
t1 <- trans_env$new(dataset = dataset, add_data = env_data_16S[, 4:11])

Error in initialize(...) : No sample names of sample_table found in env_data! Please chech the names of env_data!

At first I got it with my own data set but then went back to the example data provided (https://chiliubio.github.io/microeco/#trans_env_class) and received the same error with the data provided.

Can you give an explination on how the sample_table works?
