I am OK with the integration

{$indent}{$info.name} = (uint8_t *) erpc_malloc({$info.maxSize} * sizeof(uint8_t));
{% if generateAllocErrorChecks == true %}
{$indent}if (({$info.name} == NULL) && ({$info.sizeTemp} > 0))
{$indent}if ({$info.sizeTemp} > 0)

Still if generateAllocErrorChecks is false the issue will happen, suggest to move this check outside the {% if generateAllocErrorChecks == true %}
