Hello,
When i used :

.formParam(""“texte”"", “”“test”"")
.formParam(""“ticket”"", “”“2"”")
.formParam(""“createur”""", “”“53500"”")

I got 400 error in the application server => org.springframework.web.multipart.MultipartException: Failed to parse multipart servlet request; nested exception is java.io.IOException: org.apache.tomcat

I need help please

.formParam(""“createur”""", “”“53500"”") => you have an extra double quote after createur

Then, as you’re not sending any file but only Strings, Gatling is going to encode the body into application/x-www-form-urlencoded, not multipart/form-data, even if you force the Content-Type header.

Either don’t force the Content-Type header so that the one Gatling will generate will match the one actually used for the body, or use formUpload to send a file in “attachments”
