Error: TypeError - Cannot read properties of undefined (reading 'toString')

I tried converting HAR with Headers and Query Parameters to Powershell, which worked as expected. But when provided with body it throws this error.

Did you happen to try the same, but without newline characters in the body? I wonder if it has to do with the escape character used for newlines in PowerShell strings being a backtick instead of a backslash. Removing the newlines to see if that works would be a worthwhile test.

Another test worth running would be doubly-escaping the newlines (i.e. "text": "{\\n \"name\": \"somename\"\\n}",, since you're not trying to escape the n characters in the json property value, but in the converted string.
