compiling error -> Blynk

[no-Legend]

Hi,

just want to compile the software.
But I'm facing a problem with the compiling process.
Arduino is still aborting: Compilation error: exit status 1

Here is the full error message:
In file included from /Users/robert/Documents/_AppSupport/Arduino/libraries/Blynk/src/BlynkApiArduino.h:14, from /Users/robert/Documents/_AppSupport/Arduino/libraries/Blynk/src/BlynkSimpleEsp32.h:20, from /Volumes/ROBETRA/Documents/70_Projekte/_3d-druck/solar-weather-station/SW/weather/weather.ino:63: /Users/robert/Documents/_AppSupport/Arduino/libraries/Blynk/src/Blynk/BlynkApi.h:39:6: error: #error "Please specify your BLYNK_TEMPLATE_ID and BLYNK_TEMPLATE_NAME" 39 | #error "Please specify your BLYNK_TEMPLATE_ID and BLYNK_TEMPLATE_NAME"

I'm using the newest libraries which are able to download inside of the Arduino app.
I want to use Mqtt and no other service. No Blynk and no Thinkspeak.
Also inside the secret.h everything is marked with //
//========================= Enable Blynk, MQTT or Thingspeak =================================== //const String App = "BLYNK"; // alternative is line below //const String App = "Thingspeak"; // alternative is line above const String App = "MQTT"; // alternative is line below

Any advice hoe to solve this problem?

Cheers Robert
