I am testing Bloom 2.5.1(on Neo4j 5.3.0) with Northwind graph(made by :play northwind) according to the manual below:

[https://neo4j.com/docs/bloom-user-guide/current/bloom-tutorial/search-phrases-advanced/](https://neo4j.com/docs/bloom-user-guide/current/bloom-tutorial/search-phrases-advanced/)

I got the error below when I tested Dynamic Search pharases with parameters suggestion as the manual describes:

match (c:Customer)-[r1]-(o)-[r2]-(p)-[r3]-(cat:Category)  
where c.country = $country and cat.categoryName = $category  
return \*

"AN ERROR OCCURRED WHILE RETRIEVING SUGGESTIONS:  
Cannot read properties of undefined (reading 'toString')"

No error with "No suggestions" but it occurs when I enabled the suggestions by Label-key or Cypher query.

The query returns result after I click off the error message at the start of writing the query. But it is cumbersome and looks bad when I demo in front of Neo4j customers.

Thanks for reporting - we will investigate. Now that we've released Bloom 2.6.0, have you had a chance to confirm whether you're still experiencing the issue?

Yes, the problem is still the same in 2.6.1. I've checked the version after restarting the server.

Hi, I have experienced the same kind of error.

Have you tried to use toString function in your query ?

```auto
match (c:Customer)-[r1]-(o)-[r2]-(p)-[r3]-(cat:Category)
where c.country = toString($country) and cat.categoryName = toString($category)
return *

```
