C++ Boost GIL Library; Issue with converting PNG to JPG - c++

Question

I'm working on a small personal project that converts images from different formats for ML purposes - specifically with multi-threading in mind.
Initially, everything was working smoothly: PNGs were being converted into JPGs as expected. I then added more images to the test batch which resulted in errors.
Apologies if my grammar is off or if I'm missing any info, I'm heavily sleep deprived as I type this lol.
I attempted to add more image types to the boost::gil::any_image keyword, which did help with the majority of the test batch, but I'm now left with 3 files that will not convert.
Code being run: -> int main()
using namespace boost::gil;
any_image<gray1_image_t, gray4_image_t, gray8_image_t, gray16_image_t, gray32_image_t, gray64f_image_t, rgb8_image_t, rgb16_image_t, rgb32_image_t, rgb64f_image_t, rgba8_image_t, rgba16_image_t, rgba32_image_t, rgba64f_image_t> img;
for (int i = 0; i < f_cache_size; i++) {
std::string tmp_png = R"()" + final_cache[i];
read_image(tmp_png, img, png_tag());
container.png_to_jpg(tmp_png, img, 95);
}
-> Convert.cpp
// Converts PNG files into JPG files
void Convert::png_to_jpg(std::string fileName, boost::gil::any_image<boost::gil::gray1_image_t, boost::gil::gray4_image_t, boost::gil::gray8_image_t, boost::gil::gray16_image_t, boost::gil::gray32_image_t, boost::gil::gray64f_image_t, boost::gil::rgb8_image_t, boost::gil::rgb16_image_t, boost::gil::rgb32_image_t, boost::gil::rgb64f_image_t, boost::gil::rgba8_image_t, boost::gil::rgba16_image_t, boost::gil::rgba32_image_t, boost::gil::rgba64f_image_t> image, int quality)
{
using namespace boost::gil;
std::string jpg = R"(.jpg)";
std::string png = R"(.png)";
fileName = remove_postfix_from_string(fileName, png, jpg);
write_view(fileName, view(image), image_write_info<jpeg_tag>(quality));
}
Error code after attempting to run the program:
terminate called after throwing an instance of 'std::ios_base::failure[abi:cxx11]'
what(): dynamic_io: unsupported view type for the given file format: iostream error
Aborted (core dumped)
