Our jira software cloud can't be used after import data

Question

I first made a backup of our jira data.
Then I did some simple operations, and then I want to re-import the previously backed up data into the system.
The result is this tragedy: import failed

I am very anxious to ask for help.
Image is error message

Hello,

As it is written you do not have a project with the id 10006. Make sure that a project with such project id exists in your entities.xml file. Or delete all votes for this project in your entities.xml file

Looking at the error logs.
It seems that the error that we see is related to :
Import task failed: [There was a problem configuring the database for import. Please contact Atlassian support. org.postgresql.util.PSQLException: ERROR: insert or update on table "jiraissue" violates foreign key constraint "jiraissue_project_fkey" Detail: Key (project)=(10006) is not present in table "project".]

I went ahead and search for the project with ID = 10006, however, it seems that this project is no longer exist in your Jira.
However, based on the error message below, we can see that there is an issue with a field association
org.ofbiz.core.entity.GenericEntityException: while inserting: [GenericEntity:IssueTypeFieldAssociation][issueTypeId,10018][fieldIdentifier,customfield_10084][defaultValue,org.ofbiz.core.entity.JsonBType@59fb03cc][created,2019-02-14 10:55:55.647438][id,163][position,10520][category,primary

Now, we would like you to check something in the entities.xml file, find the corresponding entry of IssueTypeFieldAssociation, something like:
<IssueTypeFieldAssociation id="163" issueTypeId="10018" fieldIdentifier="customfield_10084" position="10520" category="primary" required="false" defaultValue="org.ofbiz.core.entity.JsonBType@59fb03cc" />
Remove the defaultValue parameters (defaultValue="org.ofbiz.core.entity.JsonBType@59fb03cc) and proceed to import again.
