Rocket Universe API请求数据类型错误：生产异常UAT正常求助

Hey there, let's dig into this issue you're facing—production throws an "Improper data type" error in TWL.VIX11 (pointing to line 5), with the process hanging at submitRequest, but UAT runs perfectly. Here's how I'd approach troubleshooting this:

1. Check RHANDLE Data Type Consistency #

• You initialized RHANDLE = "" as a string, but the createRequest function might be returning a non-string value (like a numeric handle, null, or uninitialized value) in production. UAT's API response might be consistent enough to keep RHANDLE as a valid string, but production's response is breaking this.
• Add a quick type check in production to confirm:

  CRT "RHANDLE TYPE: ":TYPE(RHANDLE)
  

  Compare this output with what you see in UAT—if the types don't match, that's a clear clue.

2. Validate createRequest Output & API Response Differences #

• The production instance of the API http://10.136.68.46:50003/WebApi/vehicle/VVV5555/icno/1111111111 might be returning an unexpected response (like an error code, empty payload, or malformed data) that causes createRequest to generate an invalid RHANDLE.
• Look closely at the RESULT value printed on line 4 in production. If createRequest failed, the error code here would mean RHANDLE wasn't properly initialized—leading to the type error when you try to print it on line 5.

3. Audit submitRequest Parameter Types #

• The parameter "AmtIn=":TEXT could be a culprit: if TEXT is a numeric type in production (but empty string in UAT), concatenating it with a string might create an invalid data type that submitRequest can't handle.
• Also, double-check if RHEAD, RDATA, and RSTAT are properly initialized in production. If these parameters require specific types (like arrays or pre-defined structures), leaving them uninitialized would trigger type mismatch errors.

4. Rule Out Environment-Specific Library/Config Differences #

• It's possible the underlying libraries handling createRequest and submitRequest are different versions between UAT and production. Production's library might have stricter type validation that UAT's doesn't.
• Check system-level configs too—things like character encoding or memory allocation rules could change how variables (like RHANDLE) are stored and interpreted across environments.
