Missing Test Step attachments, while we create a Test with Graphql mutation multiple times.

Description
If we create a Test by using Graphql Mutation, the Test Step attachments are sometimes missing.

Pre-conditions

How to reproduce

1. Execute the following Graphql query multiple times:

2. mutation
   {
       createTest(
           testType:{name:"Manual"},
           steps:
           [
           {action:"Test Desc1",data:"Test Data1",result:"Test result1",attachments:[{filename:"1_DOC!#123.doc",mimeType:"octet-stream",data:"Z2V0IGZpbGUgY29udGVudCBoZXJl"}],customFields:[]},
           {action:"Test Desc2",data:"Test Data2",result:"Test result2",attachments:[{filename:"2_DOC!#123.doc",mimeType:"application/octet-stream",data:"Z2V0IGZpbGUgY29udGVudCBoZXJl"}],customFields:[]}
           ],
           jira:
           {fields:{
           summary:"Test Summary",
           project:{key:"SEC"}
           }}
       ) {
           test{issueId,projectId,testType{id,name,kind},steps{id,action,data,result,attachments{id,filename,downloadLink},customFields{id,name,value},callTestIssueId},unstructured,gherkin,folder{name,path},scenarioType,lastModified},warnings
       }
   }

Actual result/Attachments:

The created Tests misses the Test Step attachments sometimes.

Expected result

The created Tests should contain the Test Step attachments for all the Mutations
