Hello

I would like to adapt this curl request to Gatling

```auto
curl localhost:3001/graphql \
  -F operations='{ "query": "mutation ($image: Upload!) { singleUpload(image: $image) { id } }", "variables": { "image": null } }' \
  -F map='{ "0": ["variables.file"] }' \
  -F 0=@a.txt

I tried this way but it is not accept from the server: I get : Error: "Multipart: Boundary not found"
Image001.jpg is avalaible in the "resources" folder of Gatling
The curl request works properly even from postman ou Insomnia

 exec(http("Upload")
.post("${env}/graphql")
.headers(Map("Content-Type" -> "multipart/form-data"))
.formParam("operations","{ \"query\": \"mutation ($image: Upload!) { singleUpload(image: $image) { id } }\", \"variables\": { \"image\": null } }")
.formParam("map","\"{ \"0\": [\"variables.image\"] }\"")
.formParam("0", "\"@image001.jpg\"")

Any idea ?

Thanks in advance

Thanks in advance

```

formParam is for String values.  
formUpload is for file.

Thanks for the info  
I updated to formUpload

exec(http(“Upload”)

.post("${env}/graphql")  
.headers(Map(“Content-Type” → “multipart/form-data”))  
.formParam(“operations”, “{ “query”: “mutation ($image: Upload!) { singleUpload(image: $image) { id } }”, “variables”: { “image”: null } }”)  
.formParam(“map”, “{ “0”: [“variables.image”] }”)

.formUpload(“0”, “image001.jpg”)

But still get the same error from the server

BadRequestError: Invalid JSON in theoperation multipart field ([https://github.com/jaydenseric/graphql-multipart-request-spec](https://github.com/jaydenseric/graphql-multipart-request-spec))

If i can add

From the log, the request send by Gatling is like this :

HTTP request:  
POST ${env}/graphql  
headers=  
accept: _/_  
host: ${env}  
content-type: multipart/form-data; boundary=  
content-length: 281666

multipartBody=  
StringPart: name=operations contentType=null dispositionType=null charset=UTF-8 transferEncoding=null contentId=null  
StringPart: name=map contentType=null dispositionType=null charset=UTF-8 transferEncoding=null contentId=null  
ByteArrayPart: name=0 contentType=image/jpeg dispositionType=null charset=null transferEncoding=null contentId=null filename= image001.jpg

i don’t think it suppose to be like that ?

I think your grapql query is the issue.

Correct me if I’m wrong, but $image here goes with the query, not the Gatling EL or Scala. So, maybe you can try $image there instead of $image to avoid interpretation issues.

[https://gatling.io/docs/current/session/expression\_el](https://gatling.io/docs/current/session/expression_el)

Also, you can try logging that string to the console to make sure that it actually is valid json/graphql query.

Hi Lance  
Thanks for your time  
I did try with $image but instead of $image i used $$image because it was consider as invalid escape character

But same results. ☹
