...Cause
This is caused when the entities.xml contains a CustomfieldValue entry for a text custom field with no value.
For example:
1
<CustomFieldValue id="20140" issue="15275" customfield="10706"/>Solution
To solve this issue:
Unzip the project dump zip;
Unzip the data.zip file;
Open the entities.xml file;
Remove the line with the incomplete
CustomFieldValueentry, as the example above;Zip the activeobjects.xml and entities.xml together into the data.zip again;
ℹ️ Be careful to zip just the files! If you zip the directory above it, the file structure might be changed, and a different error will happen on import;
Zip the original directories (data and attachments) with the coinfig.xml file;
Import the project.
