Unable to filter using like operator in 7.8

Camunda 7 Topics Discussion & Questions

The 7.8 version of the REST API seems to suffer to a similar bug of the 7.6 when filtering tasks by variables value.

To get a list of task filtered by a variable it is sufficient to make a call using the following parameter
taskVariables&variableName_operator_value.

In previous version filtering with ‘like’ did not work:

now, in 7.8, variable_like_value does return a status of 200 but does not correctly get the tasks.

  1. it has the same behaviour as eq if the value is complete, for example
    company_like_acme gets 10 task
    company_eq_acme gets 10 task
  2. it gets 0 tasks if the value is just a piece of our word, such as
    company_like_ac gets 0 tasks

Any news regarding this functionality?

Hi @alice,

do you mean historic task instances?
Can you past which REST request are you using?

I’m using the get task query https://docs.camunda.org/manual/7.5/reference/rest/task/get-query/, not the History one, i hope they work similarly.

GET
/engine-rest/task?active=true&processVariables=company_like_acme
if “acme” get truncated, the ‘like’ operator gets the same result as the ‘equal’ operator.

What happens if you try this:

GET /engine-rest/task?active=true&processVariables=company_like_acm%

Thanks to sdorokhova suggestion, now I’m able to search for the truncated words, many thanks.

GET
‘…/engine-rest/task?active=true&taskVariables=company_like_’+company+“%25”;

Regards,
Alice
