The data recived in byte?

Hi,

I receive frames on chirpstack application server, but it seems it received on byte but not on base64 , am I right? … and if this correct how I can change it to be received on base64 ? or even it is better to receive it as it is , but how ?
for example: I send a frame contain temperature data (e.g. temperature = 23), so when I check it on the chirpstack server or on the application server via the terminal, it represented on base64, but when I check it on the application server on the WEB, Uplink frame, I found that the frame data is on byte. how to solve this issue pls ?

Thank you

Live frame log is for debug only.
When you create integration HTTP f.e. data field in received json in base64
