transact to FundMe.withdraw errored: Invalid parameters: must provide an Ethereum address.

[Krishduttm]

I'm getting this error when im trying to fund the contract from another account. Works fine with owner account but not the second one.

It is difficult to reconstruct what might have gone wrong without context. Don't be shy to post your source code here, no paper to waste ;-)
Little tip: First click on the editors <> (code) symbol and then paste your code into the backticks. This helps with reading.

Ive pasted the code, please check it out. Thanks

... and the complete error message, please.

OK, the source code is identical to https://github.com/PatrickAlphaC/fund_me/blob/main/FundMe.sol
Do you have MetaMask running and working? Do you have at least one account on one of the test networks with some test ETH in it?

[Krishduttm]

You can see in the console i deployed successfully but i got the error in the next line when i switched account and tried to fund

[cromewar]

Are you using injected web3 or Javascript virtual machine to deploy?

[Krishduttm]

im using injected web3

[cromewar]

Just as a test, delete the cache and cookies of your browser and try again.

[Krishduttm]

Tried this and still didn't work.
NOTE -The above method will delete your remix files so make sure to backup the code locally

[n4n0b1t3]

Please check, if your second metamask account is connected. Here an example of a not connected account:

[Krishduttm]

It is connected :/

[brokenseal]

Exact same issue here

[cromewar]

As a workaround try removing the onlyOwner identifier for now, and give it a try,
