Use httpx.Response.json() to avoid charset_normalizer issues: DEBUG charset_normalizer : override steps (5) and chunk_size (512) as content does not fit (153 byte(s) given) parameters. INFO charset_normalizer : ascii passed initial chaos probing. Mean measured chaos is 0.000000 % DEBUG charset_normalizer : ascii should target any language(s) of ['Latin Based'] INFO charset_normalizer : ascii is most likely the one. Stopping the process.
