"Error locating function" which exists and it is called

[SP8EBC]

I've got an error like below

<__main__.CallGraph object at 0x7f7493927a00>
Traceback (most recent call last):
  File "/home/mateusz/Documents/___STM32/ParaTNC/STM32L476_ParaMETEO/__stackanalysis/WCS.py", line 430, in <module>
    main()

    raise Exception(f"Error locating function {fxn_name} in {tu}")
Exception: Error locating function http_client_split_hostname_and_path in ./http_client.c

The thing is that the function it is complaining about exists (static) and it is called from few places in this translation unit. Below You have an output from GCC with a source of that function. __stackanalysis.zip

/**
 * This functions splits the URL string into hostname and path
 *
 * It return a split point index which in case of
 * http://pogoda.cc:8080/meteo_backend/station/z_gss_zar/summary
 * will return an index of '/' after 8080
 *

static uint16_t http_client_split_hostname_and_path(char * input, uint16_t input_ln) {

    uint16_t out = 0xFFFF;

    uint16_t iterator = 7;

    // check if URL starts correctly
    if (*input == 'h' && *(input + 1) == 't'  && *(input + 2) == 't'  && *(input + 3) == 'p'  && *(input + 4) == ':'  && *(input + 5) == '/'  && *(input + 6) == '/') {
        for (; iterator < input_ln; iterator++) {
            if (*(input + iterator) == '/') {

                out = iterator;

                break;
            }
        }
    }

    return out;
}

Do you have a code base that can replicate the issue?

This function is located in this file: https://github.com/SP8EBC/ParaTNC/blob/master/system/src/http_client/http_client.c starting on line 92. Currently target STM32L476_ParaMETEO of that project is configured in way it generates all files required for WCS operation.
