Steps to reproduce:
Just trying to compile example from InfluxDb

Actual behavior:

  • InfluxDB Version:
  • Board/ESP chip:
  • Device Arduino SDK version:

You didn't write which device you have and which version of Arduino Core for it.
Most probably you have an obsolete version of the Arduino Core for the device.

Hello, I had similar error messages in the BasicWrite Example with Heltec Wireless Stick: https://heltec.org/project/wireless-stick/

Solution was to update the Arduino Core in the Board Manager! In my case it was ESP32, probably you need ESP8266.

This is what I got before the update:

Using board 'heltec_wireless_stick' from platform in folder: C:\Users\xxx\AppData\Local\Arduino15\packages\esp32\hardware\esp32\1.0.2
Using core 'esp32' from platform in folder: C:\Users\xxx\AppData\Local\Arduino15\packages\esp32\hardware\esp32\1.0.2

         virtual size_t readBytes(char* buffer, size_t len) override;
...
exit status 1
Error compiling for board Heltec Wireless Stick.

Afterwards, the errors were gone. Maybe this helps.

As I wrote above. You need to update ESP32 Arduino Core. Version 1.0.2 is ancient.

Yes I saw that. Just wanted to highlight that you do this via Board Manager. Not sure if this is obvious.
