Hi, after upgrade from 3.15.2 to 3.16.1 I’m not able to install single npm package pagerduty (any other packages I tried are ok, so thats strange) , npm info returns 500: npm ERR! 500 javax.servlet.ServletException: java.lang.NullPointerException: pagerduty@0.0.3 Logs: ``` 2019-04-23 11:29:01,173+0000 ERROR [qtp1900775578-530] admin org.sonatype.nexus.repository.npm.internal.NpmGroupFacet - Unable to use Cooperation to merge pagerduty for repository npm-all ``` com.fasterxml.jackson.databind.JsonMappingException: (was java.lang.NullPointerException) (through reference chain: java.util.HashMap[“readme”]) at com.fasterxml.jackson.databind.JsonMappingException.wrapWithPath(JsonMappingException.java:391) … Caused by: java.lang.NullPointerException: null at com.fasterxml.jackson.databind.deser.std.MapDeserializer.\_readAndBindStringKeyMap(MapDeserializer.java:525) … 118 common frames omitted 2019-04-23 11:29:01,175+0000 WARN [qtp1900775578-530] admin org.sonatype.nexus.repository.httpbridge.internal.ViewServlet - Failure servicing: GET /repository/npm-all/pagerduty java.lang.NullPointerException: null npm-all is a repository group which contains npm hosted repo and npm proxy repo. Package installs fine if I set registry to proxy repo directly, but fails when it set to group repository. I tried to invalidate cache, remove group repo and proxy repository and add it back, not helpful. I had no such issue on 3.15.2 Could you please help ? ---

I’m not able to reproduce this locally. From the log snippet, it looks like it’s trying to merge metadata from the hosted and proxy repositories. Is there a pagerduty package in the hosted npm repository? If so, it would seem there is something about its metadata that is causing this. Rich ---

Nope, there is no such package in the hosted npm repository (I tried to add it to hosted later to check, but removed then). I have even recreated npm group, created empty hosted npm repo, added to npm group new hosted and old proxy, turned on trace log, but have same issues: > 2019-04-23 14:35:46,007+0000 DEBUG [qtp1900775578-762] admin org.sonatype.nexus.repository.view.Router - Response: Response{status=Status{successful=true, code=200, message=‘null’}, payload=NpmContent{payload=NpmStreamPayload{stream=org.sonatype.nexus.repository.npm.internal.NpmFacetUtils$$Lambda$370/1716466894@646d1d27, size=-1, contentType=‘application/json’}, attributes=‘{etag=W/“b984cee56850df0e84d94fb148c92f57”, lastModified=2018-05-27T11:44:42.000Z, hashCodesMap={org.sonatype.nexus.common.hash.HashAlgorithm@435e0cb3=68199e7d840c034e143c9b1e0e2cf0b4048d60a2}, org.sonatype.nexus.repository.storage.Asset=Asset{metadata=AttachedEntityMetadata{schema=asset, document=#25:175921{bucket:#17:21,format:npm,last\_updated:Tue Apr 23 14:31:12 UTC 2019,attributes:[5],component:null,name:pagerduty,size:3622,content\_type:application/json,created\_by:admin,created\_by\_ip:10.20.89.5,blob\_ref:npm-public@2C42E3BA-25E6FB50-C5F3CDDF-46DD3C4B-C6BAA330:03a98f84-263b-4e8c-beac-ae092e44ba9b,last\_downloaded:Tue Apr 23 11:03:08 UTC 2019,blob\_created:Tue Apr 23 11:03:08 UTC 2019,blob\_updated:Tue Apr 23 14:31:12 UTC 2019} v3}, name=pagerduty}, org.sonatype.nexus.repository.cache.CacheInfo=CacheInfo{lastVerified=2019-04-23T14:31:12.206Z, cacheToken=‘18832280603566646’}}’}} > 2019-04-23 14:35:46,007+0000 TRACE [qtp1900775578-762] admin org.sonatype.nexus.repository.view.Router - Response headers: > 2019-04-23 14:35:46,007+0000 TRACE [qtp1900775578-762] admin org.sonatype.nexus.repository.view.Router - Last-Modified: Sun, 27 May 2018 11:44:42 GMT > 2019-04-23 14:35:46,007+0000 TRACE [qtp1900775578-762] admin org.sonatype.nexus.repository.view.Router - ETag: "W/“b984cee56850df0e84d94fb148c92f57"” > 2019-04-23 14:35:46,007+0000 TRACE [qtp1900775578-762] admin org.sonatype.nexus.repository.view.Router - No response attributes > 2019-04-23 14:35:46,007+0000 TRACE [qtp1900775578-762] admin org.sonatype.nexus.repository.npm.internal.NpmGroupPackageHandler - Member RepositoryImpl$$EnhancerByGuice$$77f8ecc9{type=proxy, format=npm, name=‘npm-public’} response Status{successful=true, code=200, message=‘null’} > 2019-04-23 14:35:46,008+0000 TRACE [qtp1900775578-762] admin org.sonatype.nexus.repository.storage.ContentValidatorSelector - Looking for content validator for format: npm > 2019-04-23 14:35:46,008+0000 TRACE [qtp1900775578-762] admin org.sonatype.nexus.repository.storage.MimeRulesSourceSelector - Looking for MIME rule source for format: npm > 2019-04-23 14:35:46,008+0000 DEBUG [qtp1900775578-762] admin org.sonatype.nexus.repository.storage.StorageTxImpl - Transitioning: OPEN -\> ACTIVE > 2019-04-23 14:35:46,008+0000 DEBUG [qtp1900775578-762] admin org.sonatype.nexus.repository.storage.StorageTxImpl - Transitioned: ACTIVE > 2019-04-23 14:35:46,008+0000 DEBUG [qtp1900775578-762] admin org.sonatype.nexus.repository.storage.StorageTxImpl - Transitioning: ACTIVE -\> OPEN > 2019-04-23 14:35:46,008+0000 DEBUG [qtp1900775578-762] admin org.sonatype.nexus.repository.storage.StorageTxImpl - Transitioned: OPEN > 2019-04-23 14:35:46,008+0000 DEBUG [qtp1900775578-762] admin org.sonatype.nexus.repository.storage.StorageTxImpl - Transitioning: OPEN -\> CLOSED > 2019-04-23 14:35:46,008+0000 DEBUG [qtp1900775578-762] admin org.sonatype.nexus.repository.storage.StorageTxImpl - Transitioned: CLOSED > 2019-04-23 14:35:46,011+0000 ERROR [qtp1900775578-762] admin org.sonatype.nexus.repository.npm.internal.NpmGroupFacet - Unable to use Cooperation to merge pagerduty for repository npm-all > com.fasterxml.jackson.databind.JsonMappingException: (was java.lang.NullPointerException) (through reference chain: java.util.HashMap[“readme”]) I have this issue right after upgrade, I don’t think metadata changed somehow.

This will take further diagnosis. I suggest opening an issue at [https://issue.sonatype.org](https://issue.sonatype.org) in the “dev - nexus” project for this. Rich ---
