Hello,
I have a question, I migrate my Test Automatique ( in Ready API) to Robotframework
For a Test I have an endpoint api Rest who upload a zip file in a process.

with in attach a zip file the import are OK
but my similar test I write with json send an error 500
```

${reponse}= POST On Session wwww /xx/api/dossier/${caseId}/import-process headers=${header} files=${files}

Hi @astrowalker2013,
Given that you are uploading a single file, maybe try it like this:
```python
${jsonprocess} ${EXECDIR}/ ******* /toto.zip
***Test Cases***
Test1
${caseId} = create a folder ${jsoncasesfile}
Import a process ${caseId}
***Keywords**
Import a process
[Documentation] This Function import a process in a folder
[Arguments] ${caseId}
${header}= Create Dictionary Content-Type=application/zip Accept-Encoding=gzip,deflate
${file}= Get File For Streaming Upload ${jsonprocess}
${reponse}= POST On Session wwww /xx/api/dossier/${caseId}/import-process headers=${header} data=${file}
```
If you have a working test case (you mentioned you are migrating your test case) what does the request headers/request body for the old test case look like? what’s different on request headers/request body when using robot framework?
Also if you can get access to the application server errors for this request that might give you a clue what the problem, i.e. it might say missing header xxx or body not correct format or something like that.
All we know for now is the server didn’t like what you sent it but no idea why, the error message `"Internal server error"` and the request path is not very helpful, but that might be by design?
Dave.

ok corrected
finaly it’s an issue of the api.
not an issue of request library
