LONG_CONTENT_WRONG_BUSINESS_TYPE

Error message

LONG_CONTENT_WRONG_BUSINESS_TYPE

What it means

Thrown in ChatEnhanceServiceImpl.saveFile when ChatFileLimitEnum.checkFileByBusinessType(fileName, businessType) returns false, i.e. the file's extension/type is not allowed for the given businessType. It wraps ResponseEnum.LONG_CONTENT_WRONG_BUSINESS_TYPE and is the upload entry point's format/business-type guard.

Solutions

1. Check ChatFileLimitEnum.checkFileByBusinessType to see which extensions are allowed for your businessType and upload a matching file.
2. Verify the client sends the correct businessType for the file being uploaded.
3. Ensure fileName includes a proper extension; rename the file if the extension is missing or wrong.
4. If the type should be supported, extend the ChatFileLimitEnum allowed-extension mapping.

Example fix

// before
if (!ChatFileLimitEnum.checkFileByBusinessType(fileName, businessType)) {
    throw new BusinessException(ResponseEnum.LONG_CONTENT_WRONG_BUSINESS_TYPE);
}
// after
if (!ChatFileLimitEnum.checkFileByBusinessType(fileName, businessType)) {
    log.warn("File type not allowed for businessType: {}, fileName: {}", businessType, fileName);
    throw new BusinessException(ResponseEnum.LONG_CONTENT_WRONG_BUSINESS_TYPE);
}

// Client-side pre-check mirroring the server rule:
if (!ChatFileLimitEnum.checkFileByBusinessType(fileName, businessType)) {
    throw new BusinessException(ResponseEnum.LONG_CONTENT_WRONG_BUSINESS_TYPE);
}

try {
    chatEnhanceService.saveFile(vo);
} catch (BusinessException e) {
    if (ResponseEnum.LONG_CONTENT_WRONG_BUSINESS_TYPE == e.getCode()) {
        // show allowed file types for this businessType to the user
    }
}

When it happens

Trigger: saveFile(vo) reads fileName and businessType from the uploaded file VO; if the extension (from fileName) is not in the allowed set for that ChatFileLimitEnum business type, BusinessException(LONG_CONTENT_WRONG_BUSINESS_TYPE) is thrown before size/count checks run.

Common situations: Uploading a .exe/.zip or other disallowed extension to a chat that only accepts documents; sending a file with the wrong businessType value (e.g. audio-type businessType with a text document); fileName missing an extension so extension matching fails; client passing an out-of-range businessType integer.
