Error 400 - Sheets to G. Calendar

Hellos people!!

I'm trying to send data from my Google Sheets to my Calendar but getting error 400. The weird part is: When I'm send the test on the setup page, everything works fine, but when comes to the Sheets, it gets the error. Even if I try to send the same data (A1 from sheets) gets the same error O.o
The prints:

Hi @GuiWeb,

Based on your Task History, I can see that the data you have mapped in Google Calendar is not coming from Google Sheets, which is why you are facing this error.

Please try to re-establish the connection with your Google Sheets spreadsheet and attempt to capture the correct response.

If you are entering the data in your Google Sheets through an API or through another application, then make sure that 'Auto Send on Schedule' is also enabled.

Also, make sure that the Trigger Column is the last column in your spreadsheet where the data is entered, so that the data entered in columns before it is also sent.
