Cannot read property 'changelogDate' of undefined

[devMaheshJava]

We're generating entities using

jhipster entity EntityName

after entering all the fields and relations, it prompted for entity audit like below

Running post run module hooks

Running JHipster Entity Audit Generator! v3.1.0

? Do you want to enable audit for this entity(PersonCompany)? Yes (selected by me)

then it threw the following error I'm updating the entity for audit PersonCompany events.js:183 throw er; // Unhandled 'error' event ^

sorry @deepu105 I didn't visited github from last 4 days the version is 4.13.3

[mkysoft]

This issue turn up while new entity created. entityConfig data property undefined for new entities.

// generators/enttiy/index.js
118          const jsonObj = this.entityConfig.data;
119          this.changelogDate = this.entityConfig.data.changelogDate || this.dateFormatForLiquibase();

We can change 118,119 and 120 like below:

          var jsonObj = {};
          if(this.entityConfig.data === undefined) {
            jsonObj = {
                "changelogDate": this.entityConfig.changelogDate,
                "entityTableName": this.entityConfig.entityTableName
            }
          } else {
            jsonObj = this.entityConfig.data;
          }
          this.changelogDate = jsonObj.changelogDate || this.dateFormatForLiquibase();

Not sure if this helps, but I've experienced this in 7.0.1 and the fix was to remove the entities from the .yo-rc.json and then they could be added back as entities using the entity json files.

[wael-sakhri]

Same problem here in 7.0.1 .. problem solved by removing entities in .yo-rc.json like proposed by @ryandanieldonovan

[steveswing]

Also having the same problem with 7.1.0 on an existing 6.10.1 monolith project using jhipster upgrade :

The issue is still there in JHipster 7.2.0. I created a repo that demonstrates the bug and filed it as a new issue over here.

[deepu105]

If you know what the issue is, a PR would be appreciated.

Thanks & Regards, Deepu

The same issue with 7.2.0 - thanks to Ryan Donovan for the suggestion above, deleting all items form the entities array in .yo-rc.json, then committing the changes, then running JHipster Online / Apply JDL Model worked correctly.

[ksilz]

I think the root issue is that the entities array of .yo-rc.json contains an entity that has no matching file in the .jhipster directory. To fix it, remove the entity (or entities) from the entities array of .yo-rc.json that have no matching file in the .jhipster directory.

[piprog]

@ksilz is on to something: it is definitely the otherwise deleted entity hanging around in the entity list in .yo-rc.json - which begs the question: wouldn't it be nice to have a delete entity command? :)
