Issue with Non-Numeric Characters in Evaluate Block

Issue with Non-Numeric Characters in Evaluate Block within Postman Flow

Hi All,

I’m working on a flow in Postman, where I need to evaluate and concatenate two variables in the Evaluate block. However, I am facing an issue where only the numeric part of the value is passed as the result, and the appended string (in my case, “TEST”) is not included in the result.

For instance, I am trying to concatenate a numeric variable (value1) with the string "TEST", and I expect the result to be something like 280922396350TEST. However, the Evaluate block is only showing the numeric value, ignoring the string part in the final result.

I’ve attached a screenshot of the flow for reference. The string is visible in the result block, but when I try to send it in the next request, only the numeric portion gets processed. Is there a setting or method I should be using to ensure that both the numeric and string portions are passed correctly?

Thank you for your assistance!

Hi @hbaran08

Welcome to the forums!

It looks like even the numerical part of the string doesn’t match the number in your logs. I think the issue here is your variable might not be setup correctly, can you double check both the send request block where the variable is attached and your underlying request? Happy to give it a look if you can attach screenshots.

Hello,

First of all, thank you for your feedback.

As an alternative I tried linking directly to the variable but the result did not change.

Hi @hbaran08

Are you running pre/post request scripts that modify this value in any way? Are you able to open the actual request in the logs and verify the value compared to what is being logged?

Hi @flows-daniel

It works,

Thank you for your valuable time and help. :raised_hands:
Best regards.
