resourceNameLike is null
Error message
resourceNameLike is null
What it means
EventDefinitionQueryImpl.eventDefinitionResourceNameLike sets a LIKE-pattern filter on the event definition resource name. It throws FlowableIllegalArgumentException when resourceNameLike is null, since a null pattern is an invalid filter value.

Solutions
- Pass a non-null pattern, using % wildcards as needed (e.g. "%my.event")
- Skip the filter call when no pattern is available instead of passing null
- Build the pattern with a default value like "%" if you intend a catch-all
Example fix
// before
query.eventDefinitionResourceNameLike(null);
// after
if (pattern != null) {
query.eventDefinitionResourceNameLike(pattern);
} Defensive patterns
Strategy: validation
Validate before calling
if (pattern == null || pattern.isEmpty()) { throw new IllegalArgumentException("pattern required for eventDefinitionResourceNameLike()"); } Type guard
boolean hasText(String s) { return s != null && !s.trim().isEmpty(); } Try / catch
try { query.eventDefinitionResourceNameLike(pattern); } catch (FlowableIllegalArgumentException e) { log.warn("pattern null, skipping filter"); } Prevention
- Sanitize user-supplied search patterns; never forward raw null/empty values
- Apply % wildcards explicitly rather than relying on the library
- Null-check dynamically built patterns before chaining the query
When it happens
Trigger: Calling eventDefinitionResourceNameLike(null), e.g. when a wildcard pattern is built dynamically from user input or an optional configuration entry that is absent.
Common situations: Pattern construction from config placeholders left unset, search UI passing through empty/null filter terms, copy-paste from exact-match call sites.
