    <p>I'm trying to insert bulk data into Neo4j using a script. After a while the script breaks with the following Exception.</p> <pre><code>PHP Fatal error: Uncaught exception 'Everyman\Neo4j\Exception' with message 'Unable to execute query [400]: Headers: Array ( [Content-Length] =&gt; 3031 [Content-Type] =&gt; application/json; charset=UTF-8 [Access-Control-Allow-Origin] =&gt; * [Server] =&gt; Jetty(6.1.25) ) Body: Array ( [message] =&gt; An identifier is used with different types. The identifier ` UNNAMED2` is used both as Relationship and as Collection [exception] =&gt; CypherTypeException [fullname] =&gt; org.neo4j.cypher.CypherTypeException [stacktrace] =&gt; Array ( [0] =&gt; org.neo4j.cypher.internal.symbols.SymbolTable.add(SymbolTable.scala:33) [1] =&gt; org.neo4j.cypher.internal.symbols.SymbolTable$$anonfun$checkNoOverlapsExist$1.apply(SymbolTable.scala:47) [2] =&gt; org.neo4j.cypher.internal.symbols.SymbolTable$$anonfun$checkNoOverlapsExist$1.apply(SymbolTable.scala:46) [3] =&gt; scala.collection.immutable.Map$Map1.foreach(Map.scala:109) [4] =&gt; org.neo4j.cypher.internal.symbols.Symbol in phar:///var/www/zomato9/application/library/neo4jphp.phar/lib/Everyman/Neo4j/Command.php on line 116 </code></pre> <p>The same query works from console and restarting the script from the same point where exception occurred works again for a while until it fails again. Catching the Exception and making the script sleep for few seconds does not break the script.</p> <p>Any suggestions on what might be happening here?</p> <p>UPDATE: Added a sample query</p> <pre><code>START a = node:?("?:?"), b = node:?("?:?") MATCH a-[c1:ACTIVITY_LIST*]-&gt;z, z-[r1:ACTIVITY_LIST]-&gt;y WHERE z.TIMESTAMP &gt;= '.$time.' AND y.TIMESTAMP &lt; '.$time.' CREATE n = {?}, clist = {COMMENT_ID: ''}, a-[:IN_?]-&gt;n, n-[:OUT_?]-&gt;b, n-[:COMMENT_LIST]-&gt;clist, z-[:ACTIVITY_LIST]-&gt;n, n-[:ACTIVITY_LIST]-&gt;y DELETE r1 RETURN n; </code></pre>

    2. COI have multiple scripts for inserting data about users, reviews, photos etc.. and its happening for all of them. As far as I can tell, this seems to be independent of the actual query because (1) Happens for multiple scripts (2) The same query works after a sleep Added a sample query

    3. COprobably some character encoding issue. could you find the specific line of data where it breaks? (you can find it simply by looking at the highest node in the crashed db and compare it to the data)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
