CCA ingestion causes error message

I think I was exceeding the maximum number of output variables allowed.

I looked into this and found that we are doing a few checks for number of input and output vars:

• Number of inputs and outputs must be less than the number of rows
• Number of inputs and outputs must be at least 1

(see code below)

Are there other limitations?

Best,
Alex

if (
      input_columns.length >= component.row_count() ||
      output_columns.length >= component.row_count()
    ) {
      dialog.dialog({
        message:
          "The number of inputs must be less than " +
          component.row_count() +
          ". The number of outputs must be less than " +
          component.row_count() +
          ". You have selected " +
          input_columns.length +
          " inputs and " +
          output_columns.length +
          " outputs.",
      });
    } else if (input_columns.length == 0) {
      dialog.dialog({
        message: "The number of inputs must be at least one.",
      });
    } else if (output_columns.length == 0) {
      dialog.dialog({
        message: "The number of outputs must be at least one.",
      });
    }
