This screen is generated by workflow builder without publishing any modules, So accessing service center log isn't available

Hi Ali,

That's not true, the Service Center error logging is always available. Check the Error Log and see if you can find this error, and check which module caused it and in which action.

Hi @Ali ElEsaily,

Could you please provide more details about the error by sharing service center log or share the OML file so I can better understand the issue?

Thanks

Hi @Ali ElEsaily  This error occurs mostly   when you are passing   string to an integer datatype. If you have a variable with Integer datatype ensure that you are passing  integer value.

Hi @Ali ElEsaily ,

Its usually occurs when you're trying to convert or parse a string to another data type, and the string doesn't follow the expected format .
Using functions like TextToInteger(), TextToDecimal() or some other conversion function, converting date format with invalid dates. 
Please validate you inputs request before parsing.

Hi @Venkatesaiya 

Thanks for your support, No parses is used and all entered values matches input fields

Hi @Ali ElEsaily ,

  • Check returned form data: Look at what data is being sent back when the group member returns the request. Pay special attention to any number or date fields.
  • Inspect filters/search logic: In the request list screen for the requester, check any logic that parses or casts strings — especially anything like TextToInteger(), TextToDate(), or direct data conversions.

  • Add exception handling/logging: Use error logs or breakpoints in Service Studio to trace where the error occurs and which input is causing it.

  • Guard against null/empty input: Add validation to ensure any values being parsed or displayed are in the expected format.

Please check workflow builder variables and ensure that the request "Return" step is passing valid values.
