sysparm_fixed_query is not working in UI Action

[jordimsant]

I have created the following UI Action:

var fUtil = new FacturacioUtils();
var tasquesFacturades = fUtil.tasquesFacturades(current.projecte.toString());
var query = 'top_task=' + current.projecte + '^sys_idNOT%20IN' + tasquesFacturades.join(',');

var url = gs.getProperty('glide.servlet.uri') + `sys_m2m_template.do
?sysparm_fixed_query=` + query + `
&sysparm_m2m_ref=x_tntsl_tmn_factur_facturacio_m2m
&sysparm_collectionID=` + current.sys_id + `
&sysparm_collection=x_tntsl_tmn_factur_factures
&sysparm_collection_key=x_tntsl_tmn_factur_factures
&sysparm_collection_related_file=planned_task
&sysparm_collection_related_field=planned_task
&sysparm_stack=no `;

action.setRedirectURL(url);

Nonetheless, when I launch this UI Action the filter does not apply. I am sure query is generating right because if I change "sysparm_fixed_query" by "sysparm_query" it works fine, and I cannot create a before query BR because the tables I am using are in scope application. Does anybody know why "sysparm_fixed_query" is not working? Do you know how to fix it?

Thanks in advance!

I suspect sysparm_fixed_query works well only when it's used in left nav module and not via redirection.
