Hello Klever team, We are experiencing a recurring issue across all our services as well as on KleverScan when using the KleverWallet browser. The error message is: Cannot read properties of null (reading ‘toString’) This occurs when attempting to load certain swap pairs (e.g., KLV-DGKO). It seems that the API sometimes returns null values instead of proper token/pair data, which leads to failures both in our frontend and in KleverScan itself. Could you please check this on your side? It looks like the issue is not related to our updates but to the data returned by the Klever API. Thank you in advance for your support. ![IMG_8031](https://europe1.discourse-cdn.com/flex013/uploads/klever/original/2X/8/8c5031e8bb5839074b6ea4db47967aed05f753dd.jpeg) ---

It seems it comes within sdk while broadcasting transaction. Stack goes to: null is not an object (evaluating ‘g.data.txsHashes’) ---

Hello @Sovkosov_Ignat , the Klever Team is on it. Have you tried to perform the same action on KleverScan by desktop browser? BTW, what end point are you calling on our API that it’s returning null value? ---

I can trace that they both are happening after `web.broadcastTransactions()` method ---

Hello @shymelon and @Sovkosov_Ignat. We apologize for the inconvenience. We are looking into it. ---

@shymelon Could you give me more details about how it works on iOS? The parameters used, the network, transaction type (deposit, claim, etc.). ---

Hello, sorry for misinformation, after careful examination i see that `null is not an object (evaluating 'g.data.txsHashes')` comes from our part as unhandled exception from failed `web.broadcastTransaction` method as an error stack trace, please ignore that. ---

Nevertheless, this issue is still relevant and we hope for a prompt resolution. We are receiving numerous reports from the community about being unable to perform transactions on Swopus, XPort, KleverScan, and Rarecanvas through the KleverWallet mobile browser (Android) ---
