Heroku Build Failing Due To Code Integrity

Question

I have an application deployed on Heroku and I have not had problems redeploying it, up until yesterday.

I had to upgrade one of the dependencies in my package-lock.json/yarn.lock files and when trying to upload it to Heroku, I get the following:

I realize the problem resides within this line:

npm ERR! code EINTEGRITY remote: npm ERR! sha1-hX/Kv8M5fSYluCKCYuhqp6ARsF0= integrity checksum failed when using sha1: wanted sha1-hX/Kv8M5fSYluCKCYuhqp6ARsF0= but got sha512-rIqbOrKb8GJmx/5bc2M0QchhUouMXSpd1RTclXsB41JdL+VtnojfaJR+h7F9k18/4kHUsBFgk80Uk+q569vjPA== sha1-sAoAIwoRCMSMFp5popGq/aOqzWM=. (7897 bytes)

but I do not know why it is occurring now or what triggered it (as it did not happen before).

I have tried searching online and clearing the cache, reading Heroku's Node.js Troubleshooting, adding an engines key to my package.json file to specify node/npm versions, but nothing works.

I have NOT upgraded Node/NPM in my development environment, so those versions are the same.

Answer 1

Per @TinNguyen's comment, I executed the following commands:

npm uninstall package_name

and then :

npm install package_name

and that seemed to fix the issue.

Answer 2

I simply deleted package-lock.json and npm modules, then run npm install.
