InputCollect$dt_mod is NULL in Robyn version 3.12.0.9002, even with example data

[krishna1072]

Project Robyn

Describe issue

I am encountering an issue where InputCollect$dt_mod is NULL when using the robyn_inputs() function, even when running the built-in example code provided by the Robyn package. This issue prevents me from proceeding with the model, as subsequent functions depend on InputCollect$dt_mod being properly populated.

Despite trying various troubleshooting steps, including:

Updating to the latest version of Robyn (3.12.0.9002)
Ensuring all package dependencies are up to date
Running the code in a clean R environment
Verifying that all variable names and data types are correct
Testing with both simulated and example data
The problem persists.

Error message: Error: InputCollect$dt_mod is NULL. There is an issue with the input data.

Provide reproducible example

Below is the code I'm using, which is based on the example from the Robyn documentation:

Load necessary libraries

library(Robyn)
library(dplyr)

Load example data

data("dt_simulated_weekly")
head(dt_simulated_weekly)

Define model inputs

InputCollect <- robyn_inputs(
dt_input = dt_simulated_weekly,
date_var = "DATE",
dep_var = "revenue",
dep_var_type = "revenue",
paid_media_spends = c("tv_S", "ooh_S", "print_S", "facebook_S", "search_S"),
paid_media_vars = c("tv_S", "ooh_S", "print_S", "facebook_I", "search_clicks_P"),
context_vars = c("competitor_sales_B"),
adstock = "geometric"
)

Check if dt_mod is NULL

if (is.null(InputCollect$dt_mod)) {
stop("InputCollect$dt_mod is NULL. There is an issue with the input data.")
} else {
print("InputCollect$dt_mod is properly populated. Proceeding to run the model.")
}

Define hyperparameters

hyperparameters <- list(
tv_S_alphas = c(0.5, 3),
tv_S_gammas = c(0.3, 1),
tv_S_thetas = c(0, 0.3),
ooh_S_alphas = c(0.5, 3),
ooh_S_gammas = c(0.3, 1),
ooh_S_thetas = c(0, 0.3),
print_S_alphas = c(0.5, 3),
print_S_gammas = c(0.3, 1),
print_S_thetas = c(0, 0.3),
facebook_I_alphas = c(0.5, 3),
facebook_I_gammas = c(0.3, 1),
facebook_I_thetas = c(0, 0.3),
search_clicks_P_alphas = c(0.5, 3),
search_clicks_P_gammas = c(0.3, 1),
search_clicks_P_thetas = c(0, 0.3)
)
InputCollect$hyperparameters <- hyperparameters

Attempt to run the model (cannot proceed due to the dt_mod issue)

OutputCollect <- robyn_run(InputCollect, ...)

Note: Since InputCollect$dt_mod is NULL, I cannot proceed to run the model using robyn_run().

Additional Details
Steps Taken:

Checked that all variables in dt_input are correctly named and match those specified in robyn_inputs().
Ensured that all required packages are installed and loaded.
Ran the code in a fresh R session to eliminate any environment issues.
Verified that the example data (dt_simulated_weekly) is correctly loaded and structured.
Observations:

The issue occurs even with the built-in example data, suggesting it may not be data-specific.
InputCollect is created, but InputCollect$dt_mod remains NULL.
No additional error messages are provided to indicate why dt_mod is NULL.
Request for Assistance
Could you please help me identify why InputCollect$dt_mod is NULL and how to resolve this issue? Any guidance on adjustments needed for Robyn version 3.12.0.9002 would be greatly appreciated.
