Update Mutation Duplicate key

[ibadass]

Hi,

Could you help me for this problem with the update query (view-apollo / viewjs):
Here is my update method:
updateCompany (id, name) {
this.$apollo.mutate({
mutation: UPDATE_COMPANY,
variables: {
username,
firstname
}
update: (cache, {data: {updateCompany}}) => {
const companies = cache.readQuery ({query: GET_COMPANIES})
companies.companies.push (updateCompany)
cache.writeQuery ({
query: GET_COMPANIES,
data: companies
})
}
})
.catch (error => {
console.error (error)
})
}

Via my UI, I can modify the data, but I get this error:

[Warn view]: Duplicate keys have been detected: '5c1ceca8348e0a0cfd82e'. This can cause an update error.

The data is edited, but the user interface displays the line twice with the same data, then I reload (manually) the page and the previously edited data is updated.

Thank you

You should not push the updated company to the companies list, but just edit the former data in cache.

Maybe you can format your code to help others read it.

Thank you very much for your reply. I just delete the part about the cache and it's ok now.
