Base64 not working with long strings

[Aamirusmani1552]

I am trying to encode my svg to base64 but i am getting that error:
('call to hashString.svgToImageURI errored: Error encoding arguments: Error: types/values length mismatch (count={"types":1,"values":12}, value={"types":["string"],"values":["1.0","no","1024px","1024px","0 0 1024 ') something like that

I am using the same svg that @PatrickAlphaC sir used but still getting this error. First i tried it on hardhat network and didn't get anything back for my tokenURI. Then i tried this on Remix IDE for encoding and got this error in return. I also copied the base64.sol in a seperate file on remix. But when i am using small string values like "

hello

" then it is giving me the encoded string.
please help

Can you add the line that is erroring?

this is my code on remix ide that i am using for converting:
('// SPDX-License-Identifier: MIT

pragma solidity ^0.8.0;
import "./base64.sol";

contract hashString{
function stringToBase64(string memory str) public pure returns(string memory){
string memory encodedSVGImage = Base64.encode(bytes(string(abi.encodePacked(str))));
return encodedSVGImage;
}
function svgToImageURI(string memory svg) public pure returns (string memory) {
string memory baseURL = "data:image/svg+xml;base64,";
string memory svgBase64Encoded = Base64.encode(bytes(string(abi.encodePacked(svg))));
return svgBase64Encoded;
}
}')

i also have code in remix ide for base64 encoding. I just copy pasted base64.sol file to seperate file in remix.

this is my code output with short string:

Code output with svg string:

it is just making problems with long strings.

code:
`// SPDX-License-Identifier: MIT

pragma solidity ^0.8.0;
import "./base64.sol";

contract hashString{
function stringToBase64(string memory str) public pure returns(string memory){
string memory encodedSVGImage = Base64.encode(bytes(string(abi.encodePacked(str))));
return encodedSVGImage;
}
function svgToImageURI(string memory svg) public pure returns (string memory) {
// example:
// ''
// would return ""
string memory baseURL = "data:image/svg+xml;base64,";
string memory svgBase64Encoded = Base64.encode(bytes(string(abi.encodePacked(svg))));
return svgBase64Encoded;
}
}`

here function svgToImageURI is giving this problem

Yes @Avinash104 i tried to do so. But couldn't figure it out 😅. I also mentioned the code second time with back ticks but still got the same result.
A little help here too please.

[Aamirusmani1552]

Please help I am stuck here for many days and not making any progress.

[Aamirusmani1552]

Or any alternate option for doing base64 encoding. Please please tell
@PatrickAlphaC or anybody.

Please wrap your code with 3 ` back ticks, it makes it easier to read

```solidity
<enter code here>
```

You don't gotta spam Pdawg G Fresh either, its the weekend and he already made a 32 hour long video for us to enjoy for free...you dont gotta bother the guy, when you could move on and come back to it later.

Be considerate is what I'm asking...He could of been getting some poontang and his phones going off all crazy cuz Aamirusmani1552 was stuck and couldn't get up. Cmon dude.

[PatrickAlphaC]

Thanks all :)

glad you were able to solve it, and thanks for the help! Yep, I won't always be there to help you out! It's good to try to learn how to solve stuff without me there. The community is often smarter than me anyways!

Maybe its the SVG your entering.

Also use double quotes "" instead of '' single quotes when imputing it in ur function on remix

Try:

"<svg version='1.1' id='Layer_1' xmlns='http://www.w3.org/2000/svg' xmlns:xlink='http://www.w3.org/1999/xlink' x='0px' y='0px' width='260px' height='244px' viewBox='0 0 260 244' enable-background='new 0 0 260 244' xml:space='preserve'><path d='M258,118v96c0,14.333-13.667,28-28,28h-84c-17.439,0-31.571-2.152-48-8c-5.073-1.806-20-8-20-8V114l66.036-77.567L150,2h12c13.294,0,22.657,10.607,22.657,23.902v7.477c0,17.065-1.028,34.115-3.078,51.057L180.906,90H230C244.333,90,258,103.667,258,118zM2,238h60V102H2V238z'/></svg>"
