I am currently using the Gemini 3.5 Flash API and encountered an issue where the returned file is empty. After retrying three times, the request still failed. I also tried reducing the size of the request file, but it still failed.
However, two other request files were processed successfully, even though those files are also quite large.
The attachments include screenshots of the API call logs and the generated file directory. All of them are files from stage2_chunk.
Below is some of the code related to the API call: from google import genai
from google.genai import types
async def generate_with_files(
self,
prompt_text: str,
*file_objects,
config: types.GenerateContentConfig | None = None,
label: str = “AI call”,
) → str:
contents = [prompt_text, *file_objects]
token_count = await self.count_tokens(*contents)
if token_count >= 0:
logger.info(“[tokens] %s → %d input tokens (model=%s)”,
label, token_count, self.model)
else:
logger.info(“[tokens] %s → count_tokens 失败，无法预估 (model=%s)”,
label, self.model)
response = await self.aclient.models.generate_content(
model=self.model,
contents=contents,
config=config or self._default_config,
)
text = response.text or “”
if not text:
_diagnose_empty_response(response, label, logger)
return text
