Jira Spreadsheet Uploader fails to create Issue for second Row

[Joshua Procious]

We have have a dashboard with a spreadsheet uploader that runs against a custom Scriptrunner script to create issues. The first rows loads correctly and always creates the issue but on second row we get error:

CreateException: Issue workflow initialization error: unable to find Issue created with workflowId '886986'. Did the IssueCreateFunction run successfully on workflow.initialize() ?

We have verified post-functions are in correct order (create issue first) and workflow has been properly published to the workflow scheme. 

There is a simultaneous error occurring that is a JQL slow query that is constructed incorrectly like "project = xyz and issue in zyx". Every time the query is returned in logs it's constructed in an impossible manner to execute. We have also verified the queries that run in the scriptrunner script which creates issue and not JQL is found there to be incorrect. 

Thanks for the help!
