Integrity requirements

• I have read all the comments in the issue template and ensured that this issue meet the requirements.
• I confirm that I have read the documentation, understand the meaning of all the configuration items I wrote, and did not pile up seemingly useful options or default values.
• I provided the complete config and logs, rather than just providing the truncated parts based on my own judgment.
• I searched issues and did not find any similar issues.
• The problem can be successfully reproduced in the latest Release

Description

When I try to pass config via stdin to xray run -dump or xray run -dump -format json, it always print {}

Reproduction Method

echo '{"api":{}}'|xray run -dump
# {}
echo '{"api":{}}'|xray run -dump -format json
# {}

echo '{"api":{}}' > test.json
xray run -dump -config test.json
# {
#    "api": {}
# }
